House Homeland Security Chairman: 'Disturbing Flags' in Orlando Shooting Case

— -- House Homeland Security Chairman Michael McCaul, said there are some “disturbing flags” in the Orlando shooting case and that his committee will conduct oversight hearings to determine whether the FBI did all it could to investigate them prior to the attack.

"There are some disturbing flags going up in this case that we're going to take a close look at," the Texas Republican said on ABC's "This Week," adding, "The FBI tells me they didn't have predication to detain or arrest" the alleged shooter, Omar Mateen, in its prior investigations of him.

"We do know he was on the radar several times saying he had affiliations with al Qaeda, terrorist organizations. We know he was close or attended the same mosque with the suicide bomber in Syria out of Florida," McCaul said.

McCaul also warned that there will likely be future attacks.

“This will not be the last attack in the United States. I'm certain that there is another individual like Mateen out there who is radicalizing as we speak,” he said.

Earlier this week, Republican Sen. John McCain said President Obama was “directly responsible” for the attack in Orlando. He later tweeted to clarify that he was referring to the president’s national security decisions, not the president himself.

McCaul did not personally blame the president, but did criticize his foreign policy. “I do think the foreign policy that's been conducted over the last three-and-a-half years since we've known about ISIS has led to this.”
