WASHINGTON — Members of Congress confronted Christopher A. Wray, the F.B.I. director, on Wednesday over an F.B.I. intelligence report that said that black extremists were targeting law enforcement because of police abuses in minority communities.

Mr. Wray met with the Congressional Black Caucus for about 90 minutes on Capitol Hill to discuss its members’ concerns about the report, which grouped together blacks who have espoused violent ideologies, some of whom went on to attack the police, under the term the “Black Identity Extremist” movement.

Representative Hakeem Jeffries, Democrat of New York, said Mr. Wray struggled to defend the report’s analysis and could not identify a single black identity extremist group.

“He was asked to publicly clarify that there is no scintilla of evidence, as far as we can tell, to provide an example of the black identity extremist movement or any groups that fall in that category,” Mr. Jeffries said. “That clarification should be made publicly, it seems to many of us, and not privately behind closed doors.”
