EXCLUSIVE – Sen. Ron Johnson (R-WI), the chairman of a Senate investigative subcommittee, will seek thousands of emails sent in the final days of the Biden administration as part of his widening investigation into the former president’s alleged cognitive decline.

In an interview, Johnson told the Washington Examiner he will send a letter to the National Archives requesting the emails, which document how President Joe Biden‘s inner circle handled pardons and other grants of clemency before he left office.
