The Senate Judiciary Committee received a sworn statement from someone described as a longtime boyfriend of Supreme Court nominee Brett Kavanaugh’s accuser Christine Blasey Ford stating that she coached someone on taking a polygraph examination.

Committee Chairman Chuck Grassley, R-Iowa, requested any audio and video recording of Ford’s polygraph test from Ford's legal team in a letter Tuesday, since she used the examination results to support her allegations when testifying before the panel Friday.

“The full details of Dr. Ford’s polygraph are particularly important because the Senate Judiciary Committee has received a sworn statement from a longtime boyfriend of Dr. Ford’s stating that he personally witnessed Dr. Ford coaching a friend on polygraph examinations,” Grassley says in his request for the materials.

During her testimony before the committee last week, Ford said under oath that she had never given any tips or advice to anyone who was planning on taking or preparing for a polygraph test.

If Ford’s former boyfriend is telling the truth in his statement, which he submitted under penalty of felony, it could implicate her in perjury.

Grassley says it is not only concerning that Ford may have lied under oath, but also brings into question the reliability of the results of her polygraph.
