Justice Dept. Declines to Back Claim Trump Is Not Under Investigation

With questions still swirling over President Trump’s unsubstantiated claims that he was wiretapped on orders of President Barack Obama, the Justice Department on Thursday declined to confirm statements a day earlier from the White House that Mr. Trump was not the target of a counterintelligence investigation.

Officials also said the White House had not relied on any information from the Justice Department in offering a statement denying the existence of an investigation.

The White House spokesman, Sean Spicer, told reporters on Wednesday that “there is no reason to believe there is any type of investigation with respect to the Department of Justice” or “ that the president is the target of any investigation whatsoever.”

But a Justice Department official, speaking on condition of anonymity because of the sensitivity of the issue, said that there was no indication that anyone at the Justice Department had given the White House that assurance.

Asked whether Mr. Trump was in fact the target of an investigation, the official offered a “no comment.”

In normal circumstances, a “no comment” from the Justice Department on the status of any investigation would be standard practice. But the controversy generated by Mr. Trump’s posts on Twitter last weekend about being wiretapped — which Mr. Obama and others have strongly denied — has generated intense scrutiny of every word on the matter.

James B. Comey Jr., the F.B.I. director, asked the Justice Department after Mr. Trump’s posts to publicly refute the notion that Trump Tower or Mr. Trump had been wiretapped. But the Justice Department has declined to do so.
