Trump, angrily, to Clinton: 'No I'm a gentleman, Hillary, go ahead'

Donald Trump argued Hillary Clinton should be in jail, while she said he was fundamentally unfit to be president, but they were falling over each other in trying to allow the other to answer first a voter's question about health care.

Not long after an explosive series of exchanges on everything from Clinton's deleted emails to Trump's treatment of women, a voter asked a question about health care.

“No I’m a gentleman, Hillary, go ahead," he responded in perhaps the sharpest fashion that phrase has ever been uttered.
