Kavanaugh is a Roman Catholic who has said religion is an important part of his life.
A week after a televised Senate Judiciary Committee hearing at which Kavanaugh and Ford transfixed the nation, the Capitol campus remained a stew of tension as the election-season cliff-hanger neared its conclusion.
Police later threatened to clear a public hallway outside her office in the Dirksen Senate Office Building and physically blocked reporters from approaching Collins as she left the office to return to the Capitol for a vote.
More than 300 people were arrested, including the comedian Amy Schumer, who is a second cousin of Senate Democrat leader Chuck Schumer, and model Emily Ratajkowski.
The scenes were unprecedented for any supreme court nominee in recent history; demonstrators gathered outside the courthouse in Washington where Kavanaugh now sits as a federal judge and walked in unison to the supreme court, where he wishes to serve. On the Senate floor, he witheringly called the accusations "uncorroborated mud".
That's put a pair of female Republican senators, Maine's Susan Collins and Alaska's Lisa Murkowski, under excruciating pressure. Neither have Republican Sens.
No Republicans have said they will vote against Kavanaugh, although four have not committed to supporting him.
During the press conference, McConnell stated that there is nothing that will satisfy Senate Democrats.
"I am an independent, impartial judge", said the headline to an opinion piece he wrote in The Wall Street Journal as the Senate moves towards a weekend confirmation vote on his nomination by President Donald Trump.
The three were briefed together on the investigation in the secure room senators were using to view the report.
It was a day when you could not tell who was winning by watching them.
If all the Democrats oppose Kavanaugh, Trump can not afford to lose the support of more than one Republican for his nominee, with Vice President Mike Pence casting a tiebreaking vote.
Chuck Schumer, the top Senate Democrat, said the report confirmed Democratic fears that "this was a very limited process that would constrain the Federal Bureau of Investigation from getting all the facts".
Sen. Joe Manchin, the only Democratic senator undecided, said he had to leave the SCIF to make room for Republicans and would return Friday morning to finish reading the report.
Trump said on Twitter the investigation was the seventh by the FBI into Kavanaugh's background, adding, "If we made it 100, it would still not be good enough for the Obstructionist Democrats". The Judiciary panel's 10 Democrats said in a statement that based on their briefing and study of the document, "That is not true".
Neither side specified what they were referring to.
Senators said the documents they examined totaled about 50 pages.
They include three people Blasey Ford says were in the house at the time of the party. That is because I forcefully and passionately denied the allegation against me.
On Thursday, a lawyer for Deborah Ramirez, who has accused Kavanaugh of exposing himself while in college, sent a letter to FBI Director Christopher A. Wray making the same claim. Some of them reported their abuse at the time, but others said nothing until now.
"I have always treated colleagues and litigants with the utmost respect".
Dr. Christine Blasey Ford accused Kavanaugh of sexually assaulting her in the 1980's during a high school house gathering. Kavanaugh has said stories of his bad behavior while drinking are exaggerated.
The President made fun of Dr Ford's inability to remember some details about what happened, news.com.au reports.
