In a sworn statement released Tuesday, an ex-boyfriend of Christine Blasey Ford, the woman who has accused Brett Kavanaugh of sexually assaulting her at a house party in 1982, directly contradicted part of Ford's sworn testimony to the Senate Judiciary Committee on Thursday.
What are the details?
During the hearing, Rachel Mitchell, the Arizona sex crimes prosecutor who questioned Ford on behalf of Republican senators, asked Ford: "Have you ever had discussions with anyone, besides your attorneys, on how to take a polygraph? And I don't just mean countermeasures, but I mean any sort of tips or anything like that?"
"Never," Ford responded, adding that she was fearful of the test itself.
"Have you ever given tips or advice to somebody who was looking to take a polygraph test?" Mitchell followed up.
"Never," Ford answered.
But Ford's ex-boyfriend, whom she dated for six years, said in his statement that he witnessed Ford coach a friend, who was applying for a job with the FBI, on how to best prepare for a polygraph examination.

"I witnessed Dr. Ford help McLean [Ford’s friend and former roommate, according to the letter] prepare for a potential polygraph exam. Dr. Ford explained in detail what to expect, how polygraphs worked and helped McLean become familiar and less nervous about the exam. Dr. Ford was able to help because of her background in psychology," the statement reveals.
The ex-boyfriend, who submitted his sworn statement under penalty of felony, also claimed Ford never told him of her alleged sexual assault, nor did she ever express a fear of flying or being confined in small places. She testified to the Judiciary Committee that she is claustrophobic, and therefore afraid of flying.
In response to the development, Senate Judiciary Committee chairman Chuck Grassley (R-Iowa) wrote Ford's attorneys Tuesday demanding they turn over evidence they have so far refused to provide the committee, specifically notes from Ford's therapist and any evidence related to Ford's polygraph test, including results and video or audio recordings.

Why is this significant?
If true, it potentially clears the path for legal repercussions. Not only is lying to Congress while under oath a crime, but so is obstructing a congressional investigation with false statements. Grassley confirmed this in a letter last week.
But it could also open the door for Ford's entire testimony to be called into question.
Indeed, one of the notable exchanges between Kavanaugh and Sen. Richard Blumenthal (D-Conn.) during last week's hearing came when the Democratic lawmaker asked Kavanaugh to define the phrase "in unibus [sic], falsus in omnibus."
The legal phrase Blumenthal referred to is "Falsus in uno, falsus in omnibus." It's English translation means "false in one thing, false in everything." Of course, Blumenthal's reason for having Kavanaugh define the phrase was to remind him that lawmakers will consider his complete testimony to be untrue if there is a single hint of deception.
The question is, are lawmakers willing to equally apply that standard to Ford?
A new investigative report also calls into question major details of Ford's story. She testified to the Senate that her fears of tight spaces — due to her alleged sexual assault — were dredged up when she and her husband installed a second front door on their Palo Alto home.
Senate Judiciary Committee ranking member Dianne Feinstein (D-Calif.) asked Ford: "Is that the reason for the second door — front door — is claustrophobia?"
Ford answered: "Correct."
More from RealClearInvestigations:
Ford never specified when the renovation took place, leaving a possible impression that it and the therapy session happened around the same time.
But documents reveal the door was installed years before as part of an addition, and has been used by renters and even a marriage counseling business.

What did McLean say?
She denied the boyfriend's allegations.
"I have NEVER had Christine Blasey Ford, or anybody else, prepare me, or provide any other type of assistance whatsoever in connection with any polygraph exam I have taken at anytime," she said in a statement provided to ABC News.
