(WASHINGTON) — Judge Ketanji Brown Jackson, the first Black woman nominated to the U.S. Supreme Court in its 233-year history, will appear on Monday before the Senate Judiciary Committee for the first of four days of high-profile confirmation hearings.

Monday’s session kicks off at 11 a.m. with 10-minute opening statements from Senate Judiciary Committee members, five-minute statements from outside introducers, and then, 10 minutes from Jackson herself.

Jackson, 51, who currently sits on the nation’s second most powerful court, the U.S. Court of Appeals for the D.C. Circuit, will face questions from the committee’s 11 Republicans and 11 Democrats over two days, starting Tuesday. On Thursday, senators can ask questions of the American Bar Association and other outside witnesses.

While Democrats have the votes to confirm President Joe Biden’s first Supreme Court nominee on their own, and hope to by the middle of April, the hearings could prove critical to the White House goal of securing at least some Republican support and shoring up the court’s credibility. Jackson has been vetted twice previously by the Judiciary Committee and twice confirmed by the full Senate as a judge — most recently last year, with three Republican votes.

Jackson, who would replace retiring Supreme Court Justice Stephen Breyer if confirmed, has spent the last month meeting with senators from both parties behind closed doors on Capitol Hill ahead of publicly testifying to her qualifications for the nation’s highest court.

Will any Republicans vote for Jackson?

Judge Jackson has been vetted twice previously by the Judiciary Committee and twice confirmed by the full Senate as a judge — most recently last year, with three Republican votes. She was also confirmed by the Senate in 2010 as vice-chair of the U.S. Sentencing Commission.

GOP Sens. Susan Collins, Lisa Murkowski and Lindsey Graham voted in favor of Judge Jackson’s confirmation to the D.C. Circuit Court of Appeals in June 2021, but after private meetings with Jackson this month, all three were noncommittal about supporting her again.

While Senate Judiciary Committee Chair Dick Durbin has said he is hopeful more than three Republicans will support the nomination this time around, GOP Whip Sen. John Thune said last week he would be surprised it that were the case.

“I think it’s important to recognize that she has been confirmed three times now, so this is not a candidate who is a blank slate to us,” Collins said after spending more than 90 minutes one-on-one with Jackson. “I will, of course, await the hearings before the Judiciary Committee before making a decision.”

No Republican senator has publicly disputed Jackson’s qualification to be a justice, though several have raised concerns about her rulings and presumed judicial philosophy.

What to expect at Monday’s hearings

Monday marks the first day of four high-profile hearings where the Senate Judiciary Committee and American people will hear from Judge Ketanji Brown Jackson — President Joe Biden’s first Supreme Court nominee and the first Black woman nominated to the nation’s highest court in its 233-year history.

The hearings will gavel in at 11 a.m. with 10-minute statements from the committee’s 11 Republican and 11 Democratic members. Following member opening statements, Judge Thomas Griffith, formerly of the U.S. Court of Appeals for the District of Columbia Circuit, and professor Lisa Fairfax of the University of Pennsylvania Carey Law School will have five minutes each to introduce Jackson, whom they know personally.

Finally, Judge Jackson will then deliver an opening statement in the afternoon for 10 minutes. ABC News will air special coverage of her remarks.

And for the first time since the pandemic, for each half-hour of the proceeding, up to 60 members of the public invited by senators will also be allowed to attend.
