A former FBI informant pleaded guilty on Monday to lying about a phony bribery scheme purportedly involving Joe Biden and his son Hunter that became central to an attempt to impeach the president in Congress.
Alexander Smirnov entered his plea to a felony charge in connection with the bogus story, along with a tax evasion charge stemming from a separate indictment accusing him of concealing millions of dollars of income.
An attorney for Smirnov, 44, declined to comment after the hearing in Los Angeles federal court.
Prosecutors and the defense have agreed to recommend a sentence of between four and six years in prison when he is sentenced next month.
Smirnov will get credit for the time he has served since his February arrest on charges that he told his FBI handler that executives from the Ukrainian energy company Burisma had paid Joe Biden and Hunter Biden $5m each around 2015.
