Ronald Hopper, an assistant agent in charge of the F.B.I.’s Tampa Division, raised the possibility that the killer was an Islamist radical, and law enforcement officials said they were investigating the massacre as a terrorist attack. The F.B.I. set up a hotline for tips.

“We do have suggestions that that individual may have leanings towards that, that particular ideology,” Agent Hopper said at a news conference. “But right now we can’t say definitively, so we’re still running everything around.”

Representative Adam B. Schiff, a California Democrat who is a member of the House Intelligence Committee, issued a statement saying law enforcement officials told him that the gunman had pledged his allegiance to the Islamic State.

Federal law enforcement officials said they had found no indication so far that the attacker was linked to any wider organization, though they and the police were investigating several possible terrorism angles, both overseas and in the United States. Court records show that Mr. Mateen was born in New York, and had been married and divorced.
