In this April 24, 2014, file photo, then-Iowa Republican senatorial candidate and former U.S. Attorney Matt Whitaker watches before a live televised debate in Johnston, Iowa. President Donald Trump announced in a tweet that he was naming Whitaker, as acting attorney general, after Attorney General Jeff Sessions was pushed out Nov. 7, 2018, as the country's chief law enforcement officer after enduring more than a year of blistering and personal attacks from Trump over his recusal from the Russia investigation.
