This weekend, rumors began to circulate about President Donald Trump’s former national security advisor Mike Flynn having made a deal with the FBI and is informing on the president.

The topic was first brought up during a panel discussion on Friday night when CNN national security analyst Juliette Kayyem pointed out that ex-campaign manager Paul Manafort, former foreign policy consultant Carter Page and longtime Trump friend Roger Stone will all go before the House Intelligence Committee to testify about their connections to Russia.

“It’s not that interesting to me because I don’t think they’ll be under oath,” Kayyem said. “The one name not mentioned is a name I mention often on this show: Mike Flynn, the former national security adviser.”

“It is starting to look like — from my sources and from open reporting — that Mike Flynn is the one who may have a deal with the FBI and that’s why we have not heard from him for some time,” she said.

Flynn, a former U.S. Army Lieutenant General, was forced to resign after it was discovered that he lied to Vice President Mike Pence about his communications with Russian Ambassador Sergey Kislyak.

Former CIA Director James Woolsey said earlier this week that he was at a secret meeting with Flynn and officials from Turkey where Flynn suggested passing on U.S. diplomatic protocols in an effort to return imprisoned Muslim cleric to Turkey.
