Ms. Powell faces a stiff test: It would be unusual for a judge to throw out a case after a defendant has pleaded guilty. She accuses the Obama Justice Department and the FBI of ambushing an unprepared Flynn at the White House. She says prosecutors withheld favorable evidence in his December 2017 guilty plea to lying to two FBI agents, one of whom is Peter Strzok, a detractor of President Trump.
She is putting the Trump-Russia saga on trial through court briefs that demand evidence on critical players such as Christopher Steele, the Hillary Clinton opposition research agent who went to the Kremlin to publish bogus charges against candidate Trump. She also wants a fuller picture of Joseph Mifsud, the Maltese professor who ingratiated himself to a Trump campaign adviser in London.
