After former White House Chief of Staff Mark Meadows submitted similar slides to the House Committee investigating the January 6th Capitol riots, a conspiracy PowerPoint presentation on how the Trump administration acted to overthrow The results of the 2020 general election provided suggestions, which aroused new attention.

The exact source of this 36-page PowerPoint document is unknown. It seems to have surfaced on the Internet for the first time in early January. Before January 6, when a group of pro-Trump supporters tried to disrupt the vote count in the election, making Joe Biden win the presidential election before the joint meeting of Congress-this report was one of the few documents outlining the reasons. one. The results were compiled and disseminated by people who overthrew the election or ignored President Donald Trump’s allies or sympathized with his baseless accusations of fraud.

The PowerPoint presentation and its allegations and assertions were pushed by Trump's ardent supporters, who repeatedly spread falsehoods about the election.

Here is what we know-and what we don't know-about the presentation, its contributors, and people who may have seen it.

It may well be, but the materials look similar.

In a letter to Meadows on Wednesday, the chairman of the committee and Democratic Rep. Benny Thompson on January 6 referred to an e-mail on January 5 involving a 38-page PowerPoint briefing titled "Election Fraud , Foreign interference, and January 6th options."

The PowerPoint document is two pages longer than the 36-page version circulating online. An assistant to the committee stated that the 38-page version was not a page-by-page content that the committee received, and that the presentation was unlikely to be the committee's main focus. Nevertheless, the title of the presentation is the same.

Meadows' lawyer George J. Terwilliger III told the New York Times and The Washington Post that Meadows submitted the document to the committee because "it has no privileges." He said Meadows received the file in an email but did not process it in any way. Twelig did not immediately respond to a request for comment.

It is not clear who sent the email to Meadows.

Meadows initially cooperated with the committee, but later stated that he would no longer be involved. The House of Representatives is expected to vote as early as Tuesday on whether to ask the Justice Department to sue Meadows for refusing to answer questions about the attack.

The statement includes unfounded assertions that China and Venezuela control the U.S. electoral system and voter fraud is widespread in eight states.

It called on the Trump administration to "declare electronic voting in all states invalid," and declare a national emergency and seize votes.

More relevant to January 6th-the constitution is the date officially calculated for the election of college votes, affirming a step to affirm the victory of the presidential election-the document calls for the then Vice President Mike Pen to rank Mike from the swing state Trump reached the seat alternate voter lost , Reject voters in these states or postpone the official vote count.

Constitutional scholars stated that Pence’s intervention had no legal basis, and some votes were recounted and the court repeatedly confirmed Biden’s victory last fall, and no evidence of widespread fraud was found.

Retired Army Colonel Phil Waldron said that he visited the White House many times after the election and he admitted that he was one of the contributors to the document. He told the Washington Post that he was part of the team that introduced the speech to lawmakers and added that he was focused on foreign vote manipulation.

Waldron starred in a movie by MyPillow CEO Mike Lindell, a major supporter and financial supporter of false election fraud allegations.

Waldron said via email that he "conducted several hours of interviews" and "publicly released slides" about the presentation in January. He did not respond to follow-up questions about the location of his interview and release. (Fox News celebrity Lara Logan posted a link to the slide on Twitter on January 5.)

Jovan H. Pulitzer has a lot of influence in the community that rejected the election, and he is also associated with this document-but he said in an email that he was not involved. The speech mentioned the retired astronaut Sidney Gutierrez as the person leading the national election fraud investigation. Gutierrez could not be immediately reached for comment.

Some passages in the presentation are part of a blog post published on November 24, 2020, by the main election denier, Patrick Byrne, the founder and former CEO of Overstock.com.

It is not yet clear, although those involved in disseminating the plan said that members of Congress as well as Trump administration officials and other allies listened to the briefing.

Waldron told The Times that a member of his team-he did not give his name-discussed the allegations in the PowerPoint file with a group of senators on January 4. Waldron told the Post that he had briefed Senator Lindsey Graham. C., at the White House.

When asked about this, Graham’s spokesperson Kevin Bishop said in an email, “Graham voted for the election.”

Waldron also told the Washington Post that he briefed Wisconsin Senator Ron Johnson and his staff before the Senate Homeland Security Committee hearing on election fraud on December 16. At that time, the Republicans controlled the Senate and Johnson served as the chairman of the committee.

In a statement obtained by NBC News, Johnson said: "My staff did not see these slides before being forwarded by the Washington Post," as part of its recent report.

He said: "Before my hearing on December 16, 2020, my staff held meetings with many people who can provide election security expertise and listened to those who were concerned about violations."

Waldron told the Washington Post that he personally briefed some members of the House of Representatives on the matter on January 5.

At the same time, Waldron told The Times and The Washington Post that he communicated with Meadows through former New York Mayor Rudy Giuliani, who was Trump’s personal lawyer. Giuliani could not be immediately reached for comment.

Waldron also told the Post that he attended an Oval Office meeting with Trump and Pennsylvania lawmakers on November 25, 2020. It is not clear whether the meeting involved any version of PowerPoint presentation or its content.
