Nine Democrats on the Senate Judiciary Committee have sent a letter to White House counsel Don McGahn and FBI Director Christopher Wray with a list of 24 people and entities they believe the FBI should speak with as part of the ongoing supplemental background investigation into Supreme Court nominee Brett Kavanaugh.

The letter, dated Monday and signed by all Democrats on the committee except for Sen. Chris Coons of Delaware, notes that in addition to the allegation made against Kavanaugh by Christine Blasey Ford, two other women have come forward with allegations of their own: Deborah Ramirez and Julie Swetnick.

“We believe that all three allegations should be included in the supplemental investigation,” the Democrats write, saying the 24 suggested people and entities should be interviewed “at a minimum.”

In addition to asking for confirmation that the background investigation will include the allegations of all three women, the Democrats want McGahn and Wray to “notify us of the scope of the investigation and what the White House directed the FBI to investigate.”

In addition to Ford, Swetnick, and Ramirez, the Democrats name Kavanaugh himself. It is unclear if Kavanaugh has been directed by the White House to cooperate or not.

Ford’s husband is named, as is Mark Judge, a friend of Kavanaugh’s who allegedly witnessed the sexual assault that took place by Kavanaugh against Ford in 1982.

Judge said Friday he is willing to cooperate with "the FBI or any law enforcement agency,” but has denied the assault took place.

P.J. Smyth and Leland Ingham Keyser are also named in the letter. Smyth is a friend of Kavanaugh’s and Keyser is a friend of Ford.

Ford has said Judge, Smyth, Keyser, and unnamed others were present at a 1982 party where Kavanaugh drunkenly pushed her into a bedroom, pinned her down, and attempted to remove her clothes before she was able to get away.

Ford testified Thursday before the Senate Judiciary Committee about what she remembered from the incident. According to a new report by the New York Times on Monday, “the White House authorized the FBI to interview anyone it deems necessary as long as the review is finished by the end of the week.”

According to the report, Ramirez, Judge, Smyth, and Keyser have already been interviewed.

“We can confirm the FBI has reached out to interview Ms. Ramirez and she has agreed to cooperate with their investigation. Out of respect for the integrity of the process, we will have no further comment at this time,” said John Clune, an attorney for Ramirez, in a statement over the weekend.

Smyth’s lawyer also said Monday in a statement that he has already been interviewed by the FBI and that he has "answered every question the FBI asked him," maintaining that he had no knowledge of the gathering in question or of "improper conduct.”

Keyser said she does not refuse the veracity of Ford’s allegation, but her lawyer said in a letter to the Senate Judiciary Committee that she does not remember the alleged incident.

An attorney for Keyser did not immediately return a request for comment.

A senior White House official told NBC that Judge has been interviewed by the FBI. Judge's attorney Barbara Van Gelder confirmed in a statement that Judge "has been interviewed by the FBI but his interview has not been completed. We request your patience as the FBI completes its investigation."

On Monday, during a press conference at the White House, President Trump said that the FBI should “interview anybody they want, but within reason.”

"I want the FBI — this is now their seventh investigation — I want them to do a very comprehensive investigation," Trump said in the Rose Garden. "Whatever that means according to the senators and the Republicans and the Republican majority, I want them to do that."

Trump also said he would let the Senate Republicans, who hold the majority on the Senate Judiciary Committee, take the lead on what they will tell the FBI to look into.

An aide to Senate Judiciary Committee Chairman Chuck Grassley, R-Iowa, told the Washington Examiner they “have not been told about when the FBI expects to complete its investigation.”
