The Senate confirmed William Barr to be the next attorney general of the United States in an 54-45 vote. Democrats had criticized Barr for a previous memo he wrote calling special counsel Robert Mueller’s probe into possible obstruction of justice and collusion between President Donald Trump’s 2016 campaign and Russia “fatally misconceived.” They also sought assurances from Barr, who will oversee Mueller’s probe, that he’d remain independent as the top law enforcement official in the nation.

This is Barr’s second stint as attorney general. He also served as attorney general under the presidency of George H.W. Bush.
