On Wednesday, handwritten notes concerning Trump National Security Adviser Gen. Michael Flynn revealed FBI agents were approaching their January 2017 interview with Flynn for the purposes of trying to prosecute him or get him fired.

The news comes as no surprise to K.T. McFarland, who served as deputy national security adviser under Flynn, who says federal agents were looking to pin a crime on Flynn and President Trump where there was none  The FBI also put the heat on McFarland to give up information it could use to incriminate Flynn or Trump.

In an interview, with Radio America's Greg Corombos, McFarland says the FBI set a perjury trap for Flynn and she knows what one looks like because they tried to set one for her too.

"They were trying to blackmail Gen. Flynn. They were trying to blackmail me to either admit guilt to crimes we did not commit or to implicate others.  In my case, it was to implicate Flynn or to implicate President Trump in crimes I didn't think they had committed," said McFarland.

She says the FBI tried to nab her in a perjury trap.  And how does a perjury trap work?

"They control all your files, all your text messages, phone logs, emails. They have them. You don't have them. They have them and they let you see a little bit here and a little bit there and then they quiz you on it.

"If you make any kind of mistake, you get the wrong date, you say, 'I think that was Tuesday night' and it was really Wednesday morning, then they can jump and say, 'Well, you should have known that. We think you're lying. Therefore, you're committing perjury," said McFarland.

Listen to the full podcast to hear the two reasons the FBI and intelligence community wanted Flynn out of the White House, what crimes the FBI wanted McFarland and others to point them too, and what needs to happen to make sure these sorts of tactics don't happen again.
