The White House has indicated to the Federal Bureau of Investigation that the testimony from Kavanaugh and Ford before the Judiciary Committee last week was sufficient, said the two people, who asked not to be identified discussing the sensitive matter.
Capitol Police have begun arresting about 300 protesters who staged a sit-in on the floor of a Senate office building's atrium. Hundreds of demonstrators were arrested, including actress Amy Schumer.
The Republican leader filed a motion setting up a Friday vote on whether to limit debate on Kavanaugh and move forward. Jeff Flake, R-Ariz., told CNN that "we've seen no additional corroborating information" and said the investigation had been comprehensive.
But crucially, two key Republican senators who are yet to say how they will vote - Jeff Flake of Arizona and Susan Collins of ME - made positive comments about the probe, which was taken by some to be a sign that they were leaning towards a "yes".
The encounter weighed on him, said Flake, who later forced Republicans to delay voting on Kavanaugh while the FBI conducts another background investigation.
The testimony revealed his "deep distress at the unfairness of how this allegation has been handled", Kavanaugh said. Cory Booker (D., N.J.) said it doesn't matter if Kavanaugh is innocent or guilty.
Senator Susan Collins, a moderate Republican from ME, said it was "a very thorough investigation".
A spokesman for Hassan declined to comment Wednesday night.
Tiebreaker Game 2: Rockies, Dodgers meet for West title
Led by a 2-run homer from Corey Bellinger, the Dodgers jumped all over the Rockies from the opening bell and never looked back. Pitcher Walker Buehler will start for the Dodgers, facing off against fellow right-hander German Marquez for the Rockies .
However, Flake and Collins have sent positive signals for Kavanaugh's confirmation earlier on Thursday, hours after the FBI submitted a report to the Capitol on its investigation into the sexual misconduct accusations.
Most Democrats opposed Mr Trump's nomination of Mr Kavanaugh from the outset. At 53, he is likely to serve on the court for decades if confirmed.
"I think it's safe to say the national spectacle the professional left has created around Judge Brett Kavanaugh's confirmation process has now reached some kind of fever pitch", he said, adding the past 17 days have been a "feeding frenzy" against Kavanaugh and his family.
Timing is everything. This supplemental FBI investigation of new claims against Kavanaugh would've happened two months ago had Senate Democrats followed standard procedures and shared the letter they received from Ford, detailing her allegations against Kavanaugh with their Republican colleagues and the FBI.
Kavanaugh, writing in an opinion piece for the Wall Street Journal, said he regretted his tone at times during last week's Senate Judiciary Committee hearing that included Christine Blasey Ford, who has accused Kavanaugh of sexually assaulted her when they were both teens.
He wrote that his testimony "reflected my overwhelming frustration at being wrongly accused". "I might have been too emotional at times", Kavanaugh wrote.
The Senate, in which the Republican have a narrow 51-49 majority, is due to vote on Kavanaugh's confirmation on Saturday.
In his testimony, Kavanaugh complained about "a calculated and orchestrated political hit fuelled with apparent pent-up anger about President Trump and the 2016 election".
"In addition to the evidence I requested in my October 2 letter, in light of recently uncovered information, please turn over records and descriptions of direct or indirect communications between Dr. Ford or her representatives and any of of the following: (1) U.S. Senators or their staffs, particularly the offices of Senators Feinstein and Hirono..."
