The No. 2 Republican in the Senate on Tuesday sharply questioned the credibility of the woman who has accused Judge Brett Kavanaugh of sexual assault, as GOP leaders indicated they will limit witnesses at next week’s hearing to just the Supreme Court nominee and his accuser.

Speaking to reporters, Sen. John Cornyn (R-Tex.) said he was concerned by “gaps” in the account of Christine Blasey Ford, a psychology professor in California, who told The Washington Post in an interview published Sunday that Kavanaugh drunkenly pinned her to a bed on her back, groped her and put his hand over her mouth at a house party in the early 1980s when the two were in high school.

“The problem is, Dr. Ford can’t remember when it was, where it was, or how it came to be,” Cornyn told reporters at the Capitol late Tuesday morning.
