Here’s what some of the senators had to say.

Cory Booker, Democrat of New Jersey and member of the Judiciary Committee

“Women and men across this country have been telling their stories, screaming into this nation hoping the national conversation will shift from abusing those who have been abused to elevating truth again,” Mr. Booker said Friday night. “This body has had a test, and we are failing that test. This body has had a chance. This body has had a responsibility, and we have surrendered that responsibility.”

Catherine Cortez Masto, Democrat of Nevada

“This nominee was interviewing for a job in front of the American people, and he was belligerent, evasive and aggressive,” she said. “This nominee who currently sits as an appellate court judge on a D.C. circuit court disregarded all demeanor and respect for impartiality and independence.”

Mike Lee, Republican of Utah and member of the Judiciary Committee

Mr. Lee, the lone Republican to hold the floor overnight, defended Judge Kavanaugh, and directly rebutted remarks made by Senator Angus King, independent of Maine, who spoke before him, criticizing the judge’s demeanor in his aggressive testimony last week before the Judiciary Committee.

“He certainly didn’t see the same thing I saw, which is someone who was seeking sincerely to defend his own record of public service, his own private conduct against great adversity, in circumstances in which he and his family have been dragged through the mud by no choice of their own,” Mr. Lee said.

Patty Murray, Democrat of Washington

“Ours was an investigation to figure out enough about what happened to determine if Brett Kavanaugh is fit to serve on the highest court in the land,” said Ms. Murray, one of the female senators who ran for office after the Anita Hill hearings in 1991. “We fell short. We did not do the American people justice.”
