"LEFFINGWELL attempted to push past me and other officers. When he was deterred from advancing further into the building, LEFFINGWELL punched me repeatedly with a closed fist"

George Washington University's Program on Extremism has a website where you can see the documents being submitted about the people apprehended by the FBI and, I think,  other law enforcement agencies.

"The Program on Extremism has launched a project to create a central database of court records related to the events of January 6, 2021. This page will be updated as additional individuals are charged with criminal activities and new records are introduced into the criminal justice system.

If you’d like to contribute to offset the costs associated with court record fees and research on this and other projects, you can support the Program’s research here."

Different people have different documents filed.  Some I've seen are (links take you to an example):

Affidavit in Support of Criminal Complaint

Statement of Facts

Criminal Complaint

Indictment

Detention Memo

 The documents I have looked at were mostly Statements of Facts, which seem to have the following general structure (I've given an example of each part):

1.  Identify the person filing the report and where they work

"On January 6, 2021, your affiant  [a person who swears to an affidavit.], Michael Attard was on duty and performing my official duties as a Special Agent. Specifically, I am assigned to the Counter-terrorism squad tasked with investigating criminal activity in and around the Capitol grounds. As a Special Agent, I am authorized by law or by a Government agency to engage in or supervise the prevention, detention, investigation, or prosecution of a violation of Federal criminal laws."  From:  https://extremism.gwu.edu/sites/g/files/zaxdzs2191/f/Aaron%20Mostofsky%20Statement%20of%20Facts.pdf

2.  Background information on what happened January 6 in the Capitol

"On January 6, 2021, a joint session of the United States Congress convened at the United States Capitol, which is located at First Street, SE, in Washington, D.C. During the joint session, elected members of the United States House of Representatives and the United States Senate were meeting in separate chambers of the United States Capitol to certify the vote count of the Electoral College of the 2020 Presidential Election, which had taken place on November 3, 2020. The joint session began at approximately 1:00 p.m. Shortly thereafter, by approximately 1:30 p.m., the House and Senate adjourned to separate chambers to resolve a particular objection. Vice President Michael R. Pence was present and presiding, first in the joint session, and then in the Senate chamber." From https://extremism.gwu.edu/sites/g/files/zaxdzs2191/f/Greg%20Rubenacker%20Statement%20of%20Facts.pdf

3.  How the agency got information about the individual being charged."

"On January 7, 2021, the FBI received several tips from the public (tipsters) that PATRICK MONTGOMERY of Littleton, Colorado, was seen in photographs posted on Facebook inside the Capitol building Senate Chambers on January 6, 2021. The persons providing the tips also indicated that MONTGOMERY had posted photographs from inside the Senate Chamber on that same day.
A tipster, who will be referred to as T-1, identified MONTGOMERY as the man circled in a photograph below, wherein he appears to be standing inside the Senate Chambers:
MONTGOMERY appears to be part of the crowd that entered the Senate Chambers on January 6, 2021, and, as explained below, MONTGOMERY is wearing the same clothes as he was wearing outside the Capitol building on January 6, 2021. Your Affiant spoke with T-1 on January 12, 2021. T-1 told your Affiant that IT is a Facebook friend of MONTGOMERY and that IT knew MONTGOMERY because they worked together as river guides for three years.
Another tipster, who will be referred to as T-2, provided a post from MONTGOMERY’S Facebook page, wherein a member of the public posted on Facebook the photograph above and a commented to MONTGOMERY asking, “Is this you? I saw it on another page and it looked like

Case 1:21-mj-00044-RMM Document 1-1 Filed 01/13/21 Page 3 of 8
you.” T-1 responded, “I have saved this photo and will be indetifying [sic] you to authorities,” to which MONTGOMERY replied, “Got nothing to hide...”
Following this post, MONTGOMERY corresponded with T-1 by email on January 7, 2021. T-1 provided the email exchange to your Affiant. MONTGOMERY’S email address contains the name of MONTGOMERY’S hunting company, Pmonte Outdoors: pmonte3006@[redacted]. In response to T-1 stating, “You have been reported to the police in DC as well as the FBI,” MONTGOMERY responded, “I’m not a scared cat or running from anything. . . . Im [sic] so deeply covered by the best Federal Defense lawyers in the country in case you chicken shit cry boys don’t want it takes to defend our freedom from these corrupt politicians.” MONTGOMERY went on to explain, “I didn’t storm the castle violently. My group was let in peacefully by the police we were talking to with respect. We came a[n]d left peacefully before the anarchist and Antifa showed up breaking shit and being hoodlums.”  From https://extremism.gwu.edu/sites/g/files/zaxdzs2191/f/Patrick%20Montgomery%20Statement%20of%20Facts.pdf       

4.  Description of the person and what that person did

"At approximately 2:30 p.m. on January 6, 2021, I was performing my official duties on the first floor of the United States Capitol building. In reacting to the crowd that had breached a window of the building, I moved to a hallway in the northwest corner of the building, i.e., the Senate wing of the Capitol building. While there, I attempted to form a barrier with other officers to stop or deter additional individuals from entering the Capitol building. In the course of this effort and while inside the Capitol building, I encountered an adult male who later identified himself to me as Mark Jefferson LEFFINGWELL. LEFFINGWELL attempted to push past me and other officers. When he was deterred from advancing further into the building, LEFFINGWELL punched me repeatedly with a closed fist. I was struck in the helmet that I was wearing and in the chest. Working with other officers, I was able to gain control over LEFFINGWELL, who attempted to struggle while being detained. I transported LEFFINGWELL to United States Capitol Police headquarters for processing. While in custody, but prior to being advised of his Miranda rights, LEFFINGWELL spontaneously apologized for striking the officer. When told that the officer who LEFFINGWELL had struck was me, LEFFINGWELL apologized to me for striking me."  From:  https://extremism.gwu.edu/sites/g/files/zaxdzs2191/f/Mark%20Jefferson%20Leffingwell%20Statement%20of%20Facts.pdf

5.  List of the specific charges.

"Based on the foregoing, your affiant submits that there is probable cause to believe that BRIAN MCCREARY violated 18 U.S.C. § 1752(a)(1) and (2), which makes it a crime to (1) knowingly enter or remain in any restricted building or grounds without lawful authority to do; and (2) knowingly, and with intent to impede or disrupt the orderly conduct of Government business or official functions, engage in disorderly or disruptive conduct in, or within such proximity to, any restricted building or grounds when, or so that, such conduct, in fact, impedes or disrupts the orderly conduct of Government business or official functions. For purposes of Section 1752 of Title 18, a “restricted building” includes a posted, cordoned off, or otherwise restricted area of a building or grounds where the President or other person protected by the Secret Service, including the Vice President, is or will be temporarily visiting; or any building or grounds so restricted in conjunction with an event designated as a special event of national significance.
Finally, your affiant submits there is also probable cause to believe that BRIAN MCCREARY violated 40 U.S.C. § 5104(e)(2), which makes it a crime to willfully and knowingly: (D) utter loud, threatening, or abusive language, or engage in disorderly or disruptive conduct, at any place in the Grounds or in any of the Capitol Buildings with the intent to impede, disrupt, or disturb the orderly conduct of a session of Congress or either House of Congress, or the orderly conduct in that building of a hearing before, or any deliberations of, a committee of Congress or either House of Congress; (E) obstruct, or impede passage through or within, the Grounds or any of the Capitol Buildings; and (G) parade, demonstrate, or picket in any of the Capitol Buildings."

When I started writing this post I went through various statements and took some excerpts to give you a sense of what they say.  As I looked at various statements I realized they followed a general pattern.  So I went back and developed the above list of examples of each of the five part of the statements.  

So, now that I've finished that, I have already given you a lot of excerpts.  But below are the ones I started out with.  

From this Statement of Fact

"TIMOTHY LOUIS HALE-CUSANELLI (HALE-CUSANELLI) of Colts Neck, New Jersey, traveled to the District of Columbia to participate in a rally and protest at the U.S. Capitol. HALE-CUSANELLI is enlisted in the United States Army Reserves, and also works as a contractor at Naval Weapons Station Earle where he maintains a “Secret” security clearance and has access to a variety of munitions.

On January 12, 2021, I received information from an individual who has been enrolled as a Confidential Human Source (“CHS”) with NCIS. The CHS reported that HALE-CUSANELLI told the CHS that HALE-CUSANELLI was present at the riot at the United States Capitol Building and, as part of the riot, he entered the Capitol building itself. HALE-CUSANELLI then showed CHS videos on his cell phone which depicted HALE- CUSANELLI making harassing and derogatory statements toward Capitol Police officers both inside and outside the Capitol building.

During our meeting on January 12, 2021, the CHS reported to me that HALE-CUSANELLI is an avowed white supremacist and Nazi sympathizer who posts video opinion statements on YouTube proffering extreme political opinions and viewpoints under the title the “Based Hermes Show.” HALE-CUSANELLI also posts similar content in other forums. Prior to traveling to the rally and protest on January 6, 2021, HALE-CUSANELLI wrote “Trust the plan, it’s the final countdown, stay tuned next episode” and 'Trust the plan, major announcement soon.'”

From this Statement of Fact

"On or about January 6, 2021, an individual called the FBI’s National Threat Operations Center to report that the individual seen in the widely circulated Getty Images photograph (Figure 1) was named ADAM JOHNSON. The caller claimed that ADAM JOHNSON was a resident of Bradenton, Florida, and that the caller knew this information because he/she shared a mutual friend with ADAM JOHNSON. The FBI conducted research on government databases and learned that there was an individual named ADAM JOHNSON associated with residences in two cities in Florida: Bradenton and Parrish (which is near Bradenton). A search of the Florida’s Department of Motor Vehicles returned ADAM JOHNSON’s driver’s license photograph. By comparing this photograph to the image of PERSON 1, your affiant reasonably believes that PERSON 1 is identical to ADAM JOHNSON.

On or about January 8, 2021, the FBI consulted with members of the Speaker’s staff and learned that before the forced entry to the Capitol building began on January 6, 2021, the Speaker’s lectern was stored in the Speaker’s Suite, located under a staircase to the third floor on the House side of the Capitol building. On or about January 7, 2021, the lectern was found by a member of the Senate staff in the Red corridor of the Senate wing off the Rotunda in the Capitol building. According to the House of Representatives’ curator, the Speaker’s lectern has a market value of more than $1,000."

From this Statement of Facts:

"SCHAFFER was among the rioters who sprayed United States Capitol Police officers with “bear spray,” a form of capsaicin pepper spray sold by many outdoors retailers, as part of their efforts to push the officers back inside the Capitol and breach the Capitol Building themselves. SCHAFFER was photographed and captured on surveillance video carrying “bear spray” and engaging in verbal altercations with Capitol Police officers inside the Capitol Building.SCHAFFER is seen holding a clear sunglasses in one photograph, and bear spray in other photographs.

The photographs show SCHAFFER in a blue hooded sweatshirt under a tactical vest with a baseball cap that reads “Oath Keepers Lifetime Member.” The “Oath Keepers” is an organization that characterizes itself as a militia of former law enforcement and military personnel and has often, as a group, urged President Trump to declare Martial Law in order to prevent the Congress from certifying the Electoral College Results.

SCHAFFER, who is the front man of the heavy metal band “Iced Earth,” has long held far-right extremist views. During an interview in 2017, SCHAFFER identified himself as an “anarchist” and referred to the federal government as a “criminal enterprise.” During that same interview, SCHAFFER stated that the 2016 Presidential election was 'rigged.'”
