Collins said in a statement that Jackson has the experience, qualifications, and integrity to serve as an Associate Justice on the Supreme Court.

The role of the Senate is to look at the experience, qualifications, and integrity of the nominee.

Collins was one of three Republicans who supported Jackson's nomination to the D.C. Circuit Court of Appeals. Jackson was nominated to the D.C. Circuit last year, and two senators voted for him. Graham is expected to vote against Jackson on the Supreme Court.

In a sign that Jackson isn't likely to garner much GOP support beyond Collins, a member of the Judiciary panel said Wednesday he wouldn't vote to confirm Jackson to the high court.

Democrats on the Judiciary Committee were hoping that Tillis would support Jackson in order to avoid a tie vote. Democratic leaders will have to take the additional step of holding a vote to discharge her nomination from the committee, burning more valuable floor time.

Collins' support for Jackson ensures that Biden's high court pick is on a glide path to confirmation but also ensures that Democrats won't need Harris to deliver a tiebreaking vote. In the event of absences, it gives Democrats a cushion. Jackson is expected to be confirmed by the Senate by the end of next week.

Six of the nine Supreme Court justices were voted for by Collins. She objected to Justice Amy ConeyBarrett's nomination to the high court because of the 2020 election. One time before Jackson's confirmation hearing last week, she met with him again.

In her statement, Collins lamented the increasingly partisan Supreme Court confirmation process and noted that in the past, senators tended to give the president more deference on high court picks.

The approach that I plan to use for Supreme Court nominations runs counter to the disturbing trend of politics.
