Christine Blasey Ford’s lawyers fired off a letter to the head of the FBI Thursday lambasting the bureau’s probe of her sex assault allegations against Brett Kavanaugh for not interviewing her or others who could back her story.

“We write to provide you with the names of several of the witnesses we requested that the FBI interview in connection with this matter,” they wrote in a four-page missive to top G-man Christopher Wray that called the investigation “a stain on the process, on the FBI and on our American ideal of justice.”

“None were contacted, nor, to our knowledge, were a dozen other names we provided to the FBI whose interviews would have challenged the credibility of Judge Kavanaugh’s testimony” to the Senate Judiciary Committee, the lawyers continued.

The witnesses include Jeremiah Hanafin, a former FBI agent and polygraph expert, who conducted a polygraph exam on Ford on Aug. 7 and found her “responses not indicative of deception,” they said.

The former fed, they added, had four independent experts review his findings, and all agreed with his conclusions.

They also named Ford’s husband, Russell Ford, whom she told about the attack during a 2012 couples therapy session.

Other witnesses they wanted interviewed included five people described as close friends of Ford whom she confided in about the alleged assault at various times between 2013 and July, when she first approached her congresswoman about the attack, which she claimed happened during a high school drinking party.

Kavanaugh, President Trump’s nominee to the Supreme Court, has repeatedly denied Ford’s accusations as well as those of two other women who accused him of sexual misconduct.

The lawyers said they were “heartened” when they learned last week that the investigation into Kavanaugh would be reopened.

“All those mentioned above, and more, could easily have been interviewed in the time allotted” but were not, read the letter, sent by attorneys Debra Katz, Lisa Banks and Michael Bromwich, which was cc’d to top senators from both parties.

Republicans on Thursday praised the probe’s report as they began reviewing the single copy provided to senators one by one, while Democrats rebuked it over the lack of fresh interviews with either Ford or Kavanaugh.

The upper chamber is set to vote on his nomination by the weekend.
