Republican Sen. Lisa Murkowski of Alaska announced that she would vote to confirm Ketanji Brown Jackson to the Supreme Court, a major bipartisan boost.
Murkowski senator announced her decision ahead of a procedural Senate vote to advance the nomination after a Judiciary Committee vote produced a tie vote.
The senator, who is up for reelection this year, joins Republican Sen. Susan Collins of Maine and Mitt Romney of Utah, who also said that they would support Jackson.
"After multiple in-depth conversations with Judge Jackson and deliberative review of her record and recent hearings, I will support her historic nomination to be an Associate Justice on the U.S. Supreme Court," the senator said in a statement.
The show of support is significant development, given that Judiciary Republicans opposed Jackson's nomination and Senate Minority Leader Mitch McConnell has reportedly encouraged his caucus to vote against the groundbreaking judicial nomination.
