President Donald Trump pardoned his former national security adviser Michael Flynn on Wednesday, ending a yearslong prosecution in the Russia investigation that saw Flynn twice plead guilty to lying to the FBI and then reverse himself before the Justice Department stepped in to dismiss his case.

The Justice Department's internal watchdog will release a highly anticipated report Monday that is expected to reject President Donald Trump's claims that the Russia investigation was illegitimate and tainted by political bias from FBI leaders. But it is also expected to document errors during the investigation that may animate Trump supporters.
