ORLANDO, Fla. (AP)- A federal prosecutor says he won't speculate on whether any charges may be brought in the investigation into the nightclub shooting in Orlando.
U.S. Attorney Lee Bentley said during a news conference Wednesday that it would be premature to speculate about any charges. He also asked people to not make threats against members of the Muslim community, saying in most cases that the threats are illegal. He did not talk about any specific threats.
The FBI urged people who have had any contact or know anything about shooter Omar Mateen to please contact them. FBI agent Ron Hopper said no piece of information is too small.
An official who was briefed on the case but insisted on anonymity to discuss a continuing investigation said authorities believe that 30-year-old U.S.-born Noor Salman knew ahead of time about Sunday's attack, but they are reluctant to charge her on that basis alone.
A U.S. official says the FBI has determined that nightclub shooter Omar Mateen was in the area of Disney World at some point before the attack unfolded, though it's unclear for what purpose.
The official briefed on the investigation who was not authorized to discuss the matter publicly and spoke Wednesday on condition of anonymity.
Orlando Mayor Buddy Dyer said Mateen drove around the Orlando area Saturday evening, going from one place to another, before he opened fire at the gay nightspot about 2 a.m. Sunday. Forty-nine people were killed and more than 50 injured.
A Senate committee is asking the FBI to turn over its files on Orlando gunman Mateen.
In a letter Wednesday to Attorney General Loretta Lynch, the Senate Committee on Homeland Security and Governmental Affairs asked the FBI to provide records related to two previously closed investigations concerning Mateen.
The committee also requested details of the placement and removal of Mateen from a terrorist watch list, any prior visits to the Pulse nightclub or Walt Disney World before the attack and his travel to Saudi Arabia.
In addition, the committee said it wanted information about Mateen's use of social media before and during the attack, and the FBI's communication with state and local law enforcement about Mateen's comments about terrorism prior to the attack.
