Highlights from Senate vote to confirm Ketanji Brown Jackson

While Democrats have emphasized the historic nature of Judge Jackson's nomination and her compelling personal story, Republicans have vowed "thorough and civil" scrutiny of her record in hundreds of cases, which several have alleged shows she is "soft on crime."

Sen. Josh Hawley, R-Mo., leveled the most pointed critique of Jackson's record so far in his opening statement Monday, accusing her of a "long record" of letting child porn offenders "off the hook" in sentencing. The White House, several independent fact-checkers, and conservative outlet The National Review have called the claims misleading and unfair.

Republicans including Sen. Marsha Blackburn, R-Tenn., have also made clear they will also take aim at Jackson's defense of an accused terrorist held at the U.S. military prison at Guantanamo Bay -- a case she was assigned to as a federal public defender. Jackson has previously explained her service as an example of belief in constitutional values.

Others indicated they planned to press Jackson to characterize her judicial philosophy, though she's said outright she doesn't have one, and to answer for progressive legal advocacy groups backing both her nomination and expanding the Supreme Court's bench.

Questioning over the next two days could prove critical to the White House goal of securing at least some Republican support for Judge Jackson's confirmation.

Three Republicans -- Sens. Susan Collins, Lisa Murkowski and Lindsey Graham -- voted in favor of Jackson's confirmation to the D.C. Circuit last June, but after private meetings with Biden's nominee this month, all three were noncommittal about supporting her again.

Jackson has been vetted twice previously by the Judiciary Committee and twice confirmed by the full Senate as a judge. She was also Senate confirmed in 2010 as vice-chair of the U.S. Sentencing Commission.

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, which she has insisted she does not have.

Even without bipartisan support, Democrats have the votes on their own for Jackson's confirmation, which party leaders have said they plan to complete before Easter.

Confirmation hearings for Judge Jackson -- the first Black woman to be considered for the U.S. Supreme Court -- continue on Tuesday at 9 a.m. when she'll face up to 19 hours of questions from Senate Judiciary Committee members over two days.

Jackson will lean on her three prior experiences being questioned by the Judiciary Committee -- more than any other nominee in 30 years -- as its 11 Republicans and 11 Democrats take turns probing her judicial philosophy, her record as a public defender and her legal opinions spanning nearly nine years on the bench.

Jackson has spent the past few weeks practicing for the spotlight during mock sessions conducted with White House staff, sources familiar with the preparations told ABC News. She also met individually with each of the committee's members and 23 other senators from both parties.

Each senator will get a 30-minute solo round of questioning on Tuesday, totaling more than 11 hours if each uses all of his or her allotted time, ahead of 20-minute rounds on Wednesday. The grilling is unlike any other for federal judges or political nominees in large part because of the lifetime tenure on the line.
