Sen. Jeff Sessions, the ranking Republican on the Judiciary Committee, announced Tuesday he will oppose Elena Kagan’s nomination to the Supreme Court. 

The Alabama senator’s decision came on the same day the judiciary panel is set to vote on whether or not to send her nomination to the full Senate floor. Writing in a USA Today op-ed, Sessions said that Kagan would place her political views ahead of her duty as a judge. 

“The American people want judges who impartially follow the text of the Constitution. They reject judges who use their power to impose their own political views — liberal or conservative — on the nation,” he wrote. “Throughout her career, Ms. Kagan has placed her politics above the law.”

Sessions had not officially stated how he would vote on Kagan’s nomination, but was expected to vote ‘no’ after criticizing her liberal politics and her lack of experience as a judge. His ‘no’ vote is not expected to prevent her nomination from being sent to the Senate. 

Court watchers will be looking to Judiciary Committee member Sen. Lindsey Graham (R-S.C.) to see whether or not he votes for Kagan. The South Carolina senator voted for President Obama’s first Supreme Court nominee, Sonia Sotomayor.
