An FBI informant has been charged with lying to his handler about ties between President Joe Biden, his son Hunter and a Ukrainian energy company.

Alexander Smirnov falsely told FBI agents in June 2020 that executives associated with the Ukrainian energy company Burisma paid Hunter and Joe Biden $5 million each in 2015 and 2016, prosecutors said Thursday.

Smirnov told the FBI that a Burisma executive had claimed to have hired Hunter Biden to “protect us, through his dad, from all kinds of problems,” prosecutors said in a statement.

The allegations became a flashpoint in Congress over the summer as Republicans demanded the FBI release the unredacted form documenting the allegations as they pursued investigations of Biden and his family. They acknowledged at the time that it was unclear if the allegations were true.
