A former FBI informant who was arrested last week on charges of lying to the bureau about the Bidens’ alleged business dealings with a Ukrainian energy company, was re-arrested Thursday after a judge deemed him a flight risk. 

Alexander Smirnov, 43, was released by a Nevada judge earlier this week. A California judge ordered him arrested again on Thursday after federal prosecutors argued he was a flight risk.

The informant, Alexander Smirnov, is "actively peddling new lies that could impact U.S. elections," federal prosecutors said Wednesday, as they appealed to a judge to keep him behind bars ahead of trial on charges alleging he lied to the FBI about a phony multimillion-dollar bribery scheme involving the Bidens and the Ukrainian energy company Burisma.
