Trump holds outdoor Vegas rally; medics and water on-hand

The campaign for former president Donald Trump has hired extra medics, and is loaded up with both water and fans as supporters gather in Las Vegas, Nevada. Temperatures are expected to exceed 100 degrees Fahrenheit. Trump is returning to Nevada, one of the top battleground states in the November election. This is his second rally since he was found guilty in a hush-money scandal. Dr. Larry Walker, former Capitol senior staffer, joins LiveNOW from FOX.
