WASHINGTON — President Donald Trump’s former personal lawyer, Todd Blanche, was sworn in Monday as attorney general after a bruising confirmation fight that exposed bipartisan concerns about the Justice Department’s direction under the Republican president. Another former Trump attorney — Emil Bove, now a federal appeals court judge — administered the oath of office to Blanche at the White House following early Saturday’s Senate confirmation vote by the narrowest of margins. Shortly after, the newly sworn-in attorney general arrived at Justice Department headquarters to cheers from employees lined up along the entrance. Under deputy attorney general and later as acting attorney general, Blanche has overseen the investigations of numerous Trump foes, including former FBI Director James Comey, whom the Justice Department indicted in April for a second time since Trump returned to the White House last year. Blanche has strongly defended the Trump administration against accusations that it has weaponized the Justice Department.
