The FBI warned U.S. Sen. Ron Johnson in August that he could be a target for Russian disinformation, but he dismissed the briefing as a political ploy, according to the senator. Johnson, an Oshkosh Republican and loyal backer of former President Donald Trump, told the Washington Post that the FBI briefing didn't include specifics and he already knew of the threat from Russia. He said he believed he was being given the briefing so it could be used against him later. As the chairman of the Homeland Security Committee, Johnson spent much of 2019 and 2020 investigating the activities of Hunter Biden, the son of now-President Joe Biden who sat on the board of a Ukrainian energy company.
