WASHINGTON — The Senate Judiciary Committee chairman on Friday rejected key concessions sought by Brett Kavanaugh’s accuser if she is to testify about her claim Kavanaugh sexually assaulted her when they were teenagers, and threatened a Monday vote by his panel on Kavanaugh’s Supreme Court nomination without a quick agreement.

Minutes before a 10 p.m. deadline set by Sen. Chuck Grassley, R-Iowa, an attorney for Christine Blasey Ford asked for another day to decide.

Lawyer Debra Katz said the time limit’s “sole purpose is to bully Dr. Ford and deprive her of the ability to make a considered decision that has life-altering implications for her and her family.”

The late-night brink-manship left in question whether Ford, a California psychology professor, would appear before the GOP-run committee and tell lawmakers and a captivated nation about her allegation that an inebriated Kavanaugh trapped her on a bed, muffled her cries and tried removing her clothes when both were teenagers in the 1980s.

Grassley turned down Ford’s request that only senators, not attorneys, be allowed to ask questions. The committee’s 11 Republicans — all men — have been seeking an outside female attorney to interrogate Ford, mindful of the election-season impression that could be left by men trying to pick apart a woman’s assertion of a sexual attack.

He also rejected her proposal that she testify after Kavanaugh, a position lawyers consider advantageous because it gives them a chance to rebut accusations.

“We are unwilling to accommodate your unreasonable demands,” Grassley said in a written statement.

Grassley’s stance underscored a desire by President Donald Trump and GOP leaders to usher the 53-year-old Kavanaugh onto the high court by the Oct. 1 start of its new session and before the November elections, when Democrats are mounting a robust drive to grab congressional control.

Friday was the latest in a string of tumultuous days for Kavanaugh, whose ascension to the Supreme Court seemed a sure bet until Ford emerged last weekend and provided details of the alleged assault.

Kavanaugh, a District of Columbia Circuit Court of Appeals judge, has repeatedly denied the accusation.

Earlier, Trump ended a week of constraint and sarcastically assailed Ford, tweeting that if the episode was “as bad as she says,” she or “her loving parents” surely would have reported it to law enforcement.

Trump’s searing reproach of the California psychology professor defied the Senate Republican strategy, and the advice of White House aides, of not disparaging her while defending his nominee and the timetable for confirming him.

The president’s tweet brought blistering rejoinders from Democrats and a mix of silence and sighs of regret from his own party.

Republican Sen. Susan Collins of Maine, who hasn’t declared support for Kavanaugh, called the remark “appalling.”

It was also the latest provocation — from a man who’s faced a litany of sexual misconduct allegations himself — of moderate female voters whose support Republicans will need to fend off a robust Democratic drive to capture congressional control in November’s elections.

At a campaign rally in Missouri later Friday, Trump didn’t mention Ford but said Kavanaugh was born to be on the Supreme Court and “it’s going to happen.”

The Judiciary panel’s top Democrat expressed fury at Grassley’s negotiating position with Ford and maintained Democrats’ effort to build the battle into an election-year issue about the treatment of women.

“Bullying a survivor of attempted rape in order to confirm a nominee — particularly at a time when she’s receiving death threats — is an extreme abuse of power,” said Sen. Dianne Feinstein of California.

Female interrogators “are sensitive to the particulars of Dr. Ford’s allegations” and would “generate the most insightful testimony and will help de-politicize the hearing,” said a letter Grassley’s staff sent Ford’s lawyers.

Grassley said he’d schedule a hearing for Wednesday, not Thursday, as Ford prefers.

“It is not fair to him or to his family to allow this situation to continue without a resolution and without an opportunity for him to clear his name,” he said about Kavanaugh.

Grassley rebuffed other Ford requests, including calling additional witnesses. Ford wants an appearance by Mark Judge, a Kavanaugh friend who Ford asserts was at the high school party and in the bedroom where Kavanaugh’s assault occurred. Ford eventually escaped.

Grassley consented to other Ford demands, including that she be provided security and that Kavanaugh not be in the hearing room when she testifies.

Ford’s request for security comes after her lawyers said she has relocated her family due to death threats. She planned to meet with FBI agents in the San Francisco area to discuss those threats, said a person close to her who would describe her plans only anonymously.

The GOP letter to Ford’s lawyers said Kavanaugh and his family also have received death threats.
