For the second time in a week, Donald Trump has made an enemy of the fire marshal at his campaign rally.

"They said in this massive building, you're not allowed to have any more than 1,000 people, and that's nonsense," the Republican presidential nominee told reporters on Monday minutes before his mid-afternoon rally in Columbus, Ohio. "We could have had four, five, six thousand people. They've all been turned away. You saw them."

Trump had invited reporters to grill him before he took the stage but those present said he ignored several questions about recent controversies before proceeding to rant against the local fire marshal.

"So you have 1,000 people in there. They won't allow any more," he told members of the press. "The fire marshal said he's not allowed to allow any more even though the building holds many thousands of people. So I just wanted to tell you that."

"That's politics at its lowest," Trump continued. "You ought to check it out, but it's really politics at its lowest."

Upon entering the venue, Trump mocked his Democratic opponent in front of the crowd for her "totally empty" rallies. Holding up a photograph of a recent Clinton campaign event, he told the audience: "Now Hillary Clinton, I have a picture here which is pretty sad. She had last week, or a couple days ago, look at it — totally empty."

Trump unloaded on the fire marshal at his rally last Friday in Colorado Springs, Colo.

"Maybe they're a Hillary person," he said of Fire Marshal Brett Lacey, who had prohibited additional rally attendees from entering the main venue after the room had reached capacity. "They don't know what the hell they're doing."

"Donald, unbelievable. Even for you. Fire Chief Lacey deserves respect, not humiliation. How about an apology?" Colorado's Democratic Gov. John Hickenlooper later wrote on Twitter.
