OBAMA: No clear evidence Orlando shooter was part of larger plot or directed by ISIS

President Barack Obama says there's no clear evidence that the shooter at an Orlando nightclub was directed to conduct his attack or part of a larger plot.

He says it appears the shooter was inspired by extremist information disseminated over the internet, and wasn't directed by ISIS.

"This is certainly an example of the kind of home-grown extremism that all of us have been so concerned about for a long time," Obama said.

Obama says the investigation is at the preliminary stages and is being treated as a terrorism investigation. He says the attack appears to be similar to last year's shooting spree in San Bernardino, California.

The president says investigators are still looking into the motivations of the shooter, including the fact that the shooting took place at a gay venue.

"We're still looking at all the motivations of the killer, but it's a reminder that regardless of race, religion, faith, or sexual orientation, we're all Americans. We need to be looking after each other and protecting each other at all times in the face of this terrible act," Obama said.

Obama spoke in the Oval Office after getting briefed on the investigation by FBI Director James Comey, Homeland Security Secretary Jeh Johnson and other officials.
