Trump just turned CNN's Jim Acosta into a martyr
On Wednesday, President Trump was in a foul mood and chose to hold an impromptu news conference that lasted almost 90 minutes. Trump said "that's enough!" and a White House intern tried in vain to take the microphone from the CNN journalist.
Police said hundreds were inside when the shooting occurred.
He said he and others smashed their way out of the bar onto a balcony and then jumped down to safety.
"It was just refreshing to see someone so gung-ho and wanting to do his job well", Mayorga said.
"We were just at the bar, having fun, dancing", she told reporters.
The sheriff said Long drove to the bar and shot an unarmed security guard who was standing outside before opening fire at random inside. They responded to a call at a house in April where the suspect was acting irrationally. But it had an extended magazine - one capable of holding more ammunition - that is illegal in California, Dean said.
"And we did just get the news that he was one of the [people] killed last night".
Long was a veteran of the war in Afghanistan, where he'd served as a machine gunner. What could not be counted on would be a gunman, armed with a Glock 21.45-caliber handgun, to begin indiscriminately firing into those throngs of happy people.
