Jeff SessionsJeff SessionsIsraeli police arrest suspect in connection to JCC bomb threats FBI has info suggesting coordination between Trump aides, Russia: report Poll: By 2 to 1 margin, registered voters reject Comey MORE (R-Ala.) to be President Trump's attorney general, a day ahead of a key vote on the nomination.
“The Attorney General must faithfully serve all Americans. After carefully reviewing Senator Sessions’ extensive record, I am not convinced that he meets that threshold standard. So I must oppose this nomination," Leahy said in a statement.
He added that he had "serious doubts" that the Alabama Republican would be able to say no to Trump and "be an independent attorney general."
Leahy's statement comes after he told a local Vermont publication on Sunday that "there’s no way I can support him."
“He’s supposed to be the chief law enforcement officer, but he talks like he’s going to be Trump’s personal attorney,” Leahy added in the interview. “He’s supposed to be the attorney for all of us."
The Senate Judiciary Committee, which Leahy is a member of, is expected to vote on Sessions on Tuesday morning after Democrats delayed his nomination for a week.
Leahy sent additional questions to Sessions last week, including about his role in drafting Trump's executive order that temporarily bans entry to the U.S. for refugees and visa-holders from seven Muslim-majority countries. Democrats, as well as a growing number of Republicans, voiced concerns over the weekend about the administration's order.
Leahy on Monday said Sessions hadn't responded to his letter.
Democrats aren't expected to be able to block Sessions's nomination. Republicans hold a majority on the Judiciary Committee, and a 52-seat majority in the Senate.
