Alan Dershowitz said Saturday on "Justice With Judge Jeanine" that the FBI knew the truth before questioning former National Security Adviser Michael Flynn.

In new documents released by the office of Special Counsel Robert Mueller last week, it was confirmed that FBI agents didn't think Flynn lied to them, although he was later charged with making false statements.

As Fox News has reported:

Flynn pleaded guilty to lying about whether he had talked to former Russian ambassador Sergey Kislyak in December 2016 on limiting the Russian government's response to former President Barack Obama's recently imposed sanctions for election meddling.

Dershowitz, a Harvard Law professor emeritus, said Saturday that the FBI was simply "giving him the opportunity to lie."

"I don't think in America we want to empower the FBI or grand juries or prosecutors to impose morality tests -- criminal morality tests -- on citizens," he said.

He added that Flynn was simply a means to the end for the FBI, and the agency's goal was to to find "low-hanging fruit" in order to squeeze Flynn.

"The obvious target here was Donald Trump -- not Flynn."

Dershowitz said that Flynn should have never pleaded guilty, but that he had no choice.

"I thought that the disclosures made by the special counsel's office did not strengthen their case, they actually weakened their case," he said.
