Documents about the criminal case against former national security adviser Michael Flynn were recently released. They show that FBI officials feared that the new Trump White House might perceive the bureau as “playing games” if it sought to interview him without disclosing exactly what it was up to.

Four pages of records were provided to Flynn’s defense attorneys last week, unsealed on Wednesday by a federal judge and they portray the internal discussions at the FBI in January 2017 about how to approach the politically explosive investigation into Flynn’s contacts with the Russian ambassador weeks earlier, during the presidential transition.

One page of handwritten notes dated the same day Flynn was interviewed, Jan. 24, 2017, records a debate about how forthcoming to be with him or others at the White House about the nature of the FBI investigation.

“If we’re seen as playing games, WH will be furious,” the notes say. “Protect our institution by not playing games.”

The notes also consist of deliberation about whether confronting Flynn with a lie in real time would be helpful to their investigation.

“What is our goal? Truth/admission or to get him to lie, so we can prosecute him or get him fired?” the notes read.

The public court filings that led to U.S. District Court Judge Emmet Sullivan’s order on Wednesday unsealing the records do not indicate who authored the handwritten notes.

They bear the initials of E.W. “Bill“ Priestap, the head of the FBI’s counterintelligence division at the time, and relate to a meeting with the bureau‘s then-deputy director, Andrew McCabe. McCabe ultimately called Flynn that day to ask him to meet with two FBI agents, Peter Strzok and Joe Pientka.

Though the notes appear to reflect an unsettled deliberation, Trump allies quickly insisted on Wednesday that they amounted to irrefutable proof that the Flynn interview was a setup.

“Flynn doesn’t need to be pardoned, he did nothing wrong, he needs to be fully exonerated with all charges dropped immediately!” Donald Trump Jr., the president’s eldest son, wrote on Twitter.

The president later himself tweeted out a Fox News story about the development.

Rep. Devin Nunes of California, the top Republican on the House Intelligence Committee, tweeted: “Clear now that General Flynn was set up by dirty cops at the highest levels of our government.”
