"Did I hear about it? You're darn right I heard about it," he told Fox News.

At least two top congressional Democrats are now calling on the FBI to investigate how the information leaked to Giuliani.

"These unauthorised and inaccurate leaks from within the FBI, particularly so close to a presidential election, are unprecedented,” Representatives Elijah Cummings and John Conyers wrote.

“For this reason, we are calling on your office to conduct a thorough investigation to identify the sources of these and other leaks from the FBI and to recommend appropriate action.”

Bad news is that New York is often a threat, the good news is that we’ve been living with this now for a decade, and we got prepared for it, and drilled for it, we take every threat seriously, so we’ll be prepared and we’ll be ready."

The crowd began chanting "USA" and "Hillary" to drown out the protester seated in the balcony.

"Hold up!" Obama shouted over and over again. He told the crowd the protester deserved their respect because he was only supporting his candidate.

"Hey listen up. I told you to focus and you're not focused right now!" the president chided the crowd.
