Well, we might know a little more about why Donald Trump was cranky on Friday.
The Republican presidential candidate had to climb a ladder out of an elevator in the Mining Exchange Hotel, where he was temporarily trapped with nine other people, delaying the start of his Colorado Springs event.
The Colorado Springs Fire Department was called to reports of a stuck elevator at the Mining Exchange Hotel in downtown Colorado Springs, according to a statement from the department.
Trump made it to his Colorado Springs event a bit late, whereupon he criticized the fire marshal for enforcing the legal limit on the number of people allowed in the venue, asking whether the official might be a Democrat.
It may have been Trump's own team's fault.
Technicians found that the elevator got stuck because someone turned the manual key while it was in motion, according to Perry Sanders Jr., an attorney who co-owns the hotel.
Trump's security team was given control of the hotel's elevators during the event, said Perry Sanders Jr., an attorney who co-owns the hotel.
"The party were model guests but security insisted on having manual control of the elevators," Sanders said.
The fire department says the firefighters opened the top elevator hatch and lowered a ladder into the elevator. Trump and the others used the ladder to climb out of the elevator to the second floor. The department says no injuries were reported.
After the occupants were rescued, technicians for the company that services the elevator determined that the machine became stuck because someone turned the manual key while the car was in motion, Sanders said.
The problem was fixed and the 4-year-old elevator was immediately put back in service, he added. The Trump campaign confirmed that the incident occurred but offered no further details.
Trump continued on to a rally in Denver later Friday night.
