Last year, as Donald Trump’s re-election bid was underway, he declared that a new book by his fiercely loyal adviser Kash Patel would serve as a “blueprint” for his next administration.

“This is the road map to ending the reign of the Deep State,” Trump said of the book on his Truth Social media platform.

Titled “Government Gangsters,” it calls for a “comprehensive cleanup” of the Justice Department and an eradication of “governmental tyranny” within the FBI by firing “the highest ranks” and “to the fullest extent of the law.” to prosecute anyone who ‘in any way abused their authority for political purposes.”

“(T)he FBI has become so thoroughly compromised that it will remain a threat to the people unless drastic action is taken,” Patel claimed in his book. Democrats “should be very afraid,” Patel wrote, as Trump and his allies battle “the Deep State” — what conspiracy theorists claim is a cadre of career government employees who work together to secretly manipulate policy and destroy elected leaders. undermine.

Following Trump’s historic re-election last week, media speculation has suggested that Patel, a former Defense Department official, could be considered to become Trump’s attorney general or CIA director — or even become the current FBI director. could replace director Christopher Wray, whom Trump has reportedly held. promised to shoot.

“President Trump called (my book) the 2024 roadmap, and now let’s put it into practice,” Patel said in a podcast on Thursday, without indicating whether he himself could play a high-level role in the new administration .

A spokesperson for Trump’s transition team did not respond to a request for comment from ABC News.

Patel’s closeness to Trump and Trump’s public embrace of Patel’s book underscore how a major shakeup could be coming for the Justice Department and FBI.

Here’s what Patel said about what new leadership could do.

Fire and possibly indict FBI and DOJ officials

Patel, who was once a prosecutor in the Justice Department’s National Security Division, has long accused FBI and Justice Department leaders of exploiting their authority to boost Democrats and Republicans — especially Trump – to undermine.

There was a “two-tiered legal system,” Patel has routinely said.

He often highlights his later work as a congressional investigator, when he helped lead House Republicans’ investigation into “Russiagate” — which, as he describes it, exposed FBI misconduct in its investigation of 2016 into alleged ties between Trump’s presidential campaign and Russia.

That work led to Patel joining the Trump administration in 2019, and in the final year of Trump’s presidency, Patel was named acting deputy director of national intelligence — the second-in-command of the entire U.S. intelligence community — and then head of the American intelligence service. staff of the acting U.S. Secretary of Defense, a position that critics claimed he was not qualified to hold.

A special investigation launched by the Justice Department during Trump’s first term concluded that “senior FBI personnel” and federal prosecutors who worked on the Russia-related investigation had “demonstrated a serious lack of analytical rigor” regarding politically contaminated information, and had failed to ‘adequately investigate matters’. or question this information before launching a massive investigation into Trump and his associates, including the interception of communications from a former Trump adviser.

In its own report on the matter, the Justice Department’s Office of Inspector General said that while it found “fundamental flaws” and significant “failures” in the FBI investigation, it found no evidence that “political bias whether inappropriate motivation influenced the research”. , including the decision to intercept those communications.

Still, Patel said in his book that “all those who manipulated evidence (or concealed exculpatory information) should be charged.

He also alleged that the Justice Department “abused prosecutorial discretion” by refusing to charge Hillary Clinton for compromising classified information through her use of a private email server, and by refusing to charge the son of President Joe Biden, Hunter Biden, for what Patel describes. as influence-peddling — as he sued Trump ally Steve Bannon over his refusal to comply with a subpoena from the House panel investigating the Jan. 6, 2021 attack on the U.S. Capitol, and also indicted many of Trump’s supporters who were at the Capitol that day.

“Those specific prosecutors and units within the department that selectively apply the law must be removed and brought under control,” Patel wrote in his book.

In a campaign video released last year, Trump promised that if re-elected, he will “immediately reissue a 2020 executive order” that gives him the power “to remove rogue bureaucrats.”

“And I will exercise that power very aggressively,” he declared.

Trump also said he will “completely reform” the legal system that overturned the FBI’s 2016 and 2017 requests to intercept his former adviser’s communications.

Eliminate ‘huge’ amounts of security clearances

Two months ago, Patel said on another podcast that anyone involved in “Russiagate” should have their security clearances stripped.

According to Patel, there is a “vast” list of such government officials, from the FBI and the Justice Department to the CIA and the US military.

“They all still have consent,” including those who left government for private sector jobs, so “everyone” should lose their consent, Patel said.

Patel said he personally “recommended” to Trump that the new administration also revoke any security clearances still held by 51 then-intelligence officials, including former Director of National Intelligence James Clapper and former CIA Director John Brennan, who in October 2020, just weeks before the 2020 presidential election, he signed a letter rejecting the public release of emails from Hunter Biden’s laptop as part of a “Russian information operation’.

“We would like to emphasize that we do not know whether the emails… are real or not and that we have no evidence of Russian involvement,” they wrote. “But if we’re right, this is Russia trying to influence the way Americans vote in this election, and we strongly believe Americans should be aware of that.”

Trump and his allies have accused the 51 former intelligence officials of trying to influence the 2020 election themselves. And that’s why Patel wants Trump to deprive them of their consent.

“Because it’s justified,” Patel said. “It’s not an act of revenge. They’ve had the opportunity to withdraw, and all 51 of them have doubled and tripled. So withdraw them. I think he will.”

‘Close’ the FBI headquarters

Speaking on Thursday’s podcast about the FBI headquarters in Washington, D.C. — where more than 7,000 agents, analysts, administrative staff and other employees work — Patel said the new Trump administration needs to “close that building.”

“Open it the next day as a museum for the Deep State,” he added.

Patel said the FBI would then have to leave about 50 of its staff somewhere in Washington to keep the bureau running, and send thousands of other employees into the field to join the 16,000 employees already there.

Meanwhile, Patel said in his book that the Justice Department should “dramatically limit” the number of cases it prosecutes in Washington because Washington is “arguably the most liberal jurisdiction in America.”

Still releasing classified documents

In Thursday’s podcast, Patel described Trump’s election victory as a “mandate for the truth” about “the corruption” within the government.

Therefore, he said, the new Trump administration should “remove all remaining documents that have been blocked” by the Biden administration and by “Deep State” efforts by other administrations.

Patel has long called for the disclosure of unreleased documents from the FBI investigation into Trump and alleged ties to Russia.

On January 19, 2021, Trump’s last full day in office, the outgoing president announced he had released a folder containing many of those documents. But for reasons still unclear, none of the documents were ever officially released.

Now, again as president, Trump can “make public the documents that these people have written for decades, enabling (their) corrupt activities,” Patel said Thursday.

“He’ll come in there and maybe give them the Epstein list, and maybe the P. Diddy list,” Patel added, referring to documents on late sex offender Jeffrey Epstein and hip-hop mogul Sean “Diddy” Combs, who denies wrongdoing in the sexual abuse cases recently filed against him and maintains his innocence on the criminal charges he faces.

In the campaign video released last year, Trump promised to create a “Truth and Reconciliation Commission” that will “declassify and publish all documents involving Deep State espionage, censorship and corruption.”

It’s all part of “my plan to dismantle the Deep State and reclaim our democracy from Washington corruption once and for all,” he said.
