The FBI has concluded its investigation into the sexual misconduct allegations against Supreme Court nominee Brett Kavanaugh. Its report was sent to the White House and the Senate.

Here's what we know.

What is in the report?

The White House did not outline what was in the report and said privacy laws prevented the information from becoming public. Spokesman Raj Shah confirmed that the FBI did comprehensive interviews with nine witnesses, but did not provide names.

Six people have separately confirmed that they were interviewed by the FBI:

Deborah Ramirez, who alleged that Kavanaugh exposed himself to her at a dorm party while they were freshmen at Yale University

Mark Judge, a high school classmate of Kavanaugh's who Christine Blasey Ford alleges was in the room when Kavanaugh assaulted her at a gathering when they were both teenagers

Leland Keyser, a friend of Ford's who Ford says was present at the gathering where she was allegedly attacked

Patrick "P.J. Smyth, who Ford alleges was also at the party where she was attacked

Tim Gaudette, a Kavanaugh high school classmate who hosted a party in 1982 that was attended by some of the same people Ford alleges were present the night she was attacked

Chris Garrett, a Kavanaugh classmate who was attended Gaudette's 1982 party

A one-page executive summary of the investigation, released Thursday night by Sen. Chuck Grassley, R-Iowa, chairman of the Senate Judiciary Committee, indicated that the FBI "decided to reach out to eleven people, ten of whom agreed to be interviewed."

The other four people were not identified by name. They included an attorney for one of the witnesses in the Ford complaint, two alleged eyewitnesses named by Ramirez and a close college friend of Ramirez, according to the summary.

Shah said, "I can't outline the details of the background investigation," but indicated that nothing in the documents disqualified Kavanaugh.

Who gets to see the report?

All 100 senators will be allowed to read the report in a secure room in the U.S. Capitol.

According to a preliminary plan, the Republicans will get to read the report for an hour, and then Democrats will get to read the report for an hour.

In addition to the senators, a handful of Senate aides may view the FBI's findings, too.

Senate Democrats are expected to speak about the report later on Thursday morning.

What does this mean for Kavanaugh's nomination?

Regardless of what is in the report, the process for a vote on Kavanaugh's nomination has already been set in motion.

Senate Majority Leader Mitch McConnell filed a motion Wednesday night that ends debate on the nomination. Essentially, that means a procedural vote could take place as soon as Friday, and a final up-or-down vote could take place on Saturday afternoon.

In his executive summary, Grassley concluded, "The Supplemental Background Investigation confirms what the Senate Judiciary Committee concluded after its investigation: there is no corroboration of the allegations made by Dr. Ford or Ms. Ramirez."

But four senators on both sides of the aisle are still undecided about how they will vote on Kavanaugh. Republicans Jeff Flake of Arizona, Susan Collins of Maine and Lisa Murkowski of Alaska have not stated how they will vote. Neither has Democrat Joe Manchin of West Virginia.
