FBI probe is the next battle in war over Kavanaugh

(Adds release of Kavanaugh interview, paragraph five)

WASHINGTON, Sept 30 (Reuters) - Democratic U.S. senators expressed concern on Sunday over reports the White House was working with Republicans to narrow the scope of an FBI investigation into sexual assault allegations against Supreme Court nominee Brett Kavanaugh.

President Donald Trump bowed to pressure from moderate members of his Republican Party on Friday and ordered the probe after Christine Blasey Ford, a university professor, detailed her allegations at a Senate hearing that Kavanaugh assaulted her in 1982, when the two were in high school.

The stunning reversal capped two weeks of allegations, followed by furious denials, that roiled prospects for Trump's nominee, a conservative federal appeals court judge once expected to easily become the second Trump nominee to win a lifetime appointment to the top U.S. court.

Kavanaugh has denied Ford's accusation, as well as those of two other women.

Separately, the Senate Judiciary Committee made public late on Sunday a previously unreleased interview with Kavanaugh from Sept. 26, before a public hearing with Ford, in which he denied all the allegations against him and committee Democrats declined to ask questions, saying they felt the FBI should investigate the allegations.

Republicans, who are trying to retain control of the U.S. Congress in November elections, are seeking to balance their desire for another conservative justice on the court with sensitivity about how they handle sexual misconduct allegations amid the reverberations of the #MeToo movement.

It did not take long, however, for the FBI probe to become an object of partisan division.

A White House official, speaking on condition of anonymity, told Reuters the White House had defined the parameters of the probe for the FBI and that the investigation would start with interviews with only four people.

NBC News, the New York Times and the Wall Street Journal previously reported that the White House was constraining the investigation, prompting Democrats on the Senate Judiciary Committee to express concern.

Senator Dianne Feinstein, the panel's top Democrat, wrote to White House counsel Donald McGahn and FBI Director Christopher Wray and asked that the committee be provided with a copy of the written directive the White House sent to the FBI, as well as the names of any additional witnesses or evidence if the probe is expanded.

The White House did not respond immediately to a request for comment.
