Senate confirmation hearings began Tuesday for William Barr, President Trump’s nominee for attorney general to replace Jeff Sessions, who was fired in November. Barr served as attorney general for George H.W. Bush from 1991 to 1993, but senators asked few questions about Barr’s past record while focusing heavily on his views about special counsel Robert Mueller’s probe into Russian meddling in the 2016 election. Barr vowed to allow Mueller to complete his probe, but suggested Mueller’s long-awaited report might not be made public. He also defended writing an unsolicited memo last year to Deputy Attorney General Rod Rosenstein in which he criticized Mueller’s investigation. We’ll have much more on William Barr’s confirmation hearings later in the broadcast.
