For the past year, defenders of the FBI have consistently downplayed the significance of an FBI staff lawyer falsifying evidence in the government’s investigation into Donald Trump’s relationship with Russia. They argue Kevin Clinesmith’s crime of altering a CIA document to obscure the fact that former Trump campaign aide Carter Page worked for U.S., not Russian, intelligence was a rare lapse in judgment by an overworked bureaucrat. It was not, his apologists say, part of any broader conspiracy to conceal exculpatory information from surveillance court judges, who never learned of Page’s history with the CIA before approving FBI warrants to wiretap him as a suspected Russian agent.
