When Glenn decided to take a few phone calls from Donald Trump supporters, he probably wasn’t expecting one of the spookiest calls of his life. Nate from Virginia called in to Glenn’s radio program Wednesday to explain why he was voting for Trump.

The call took an unexpected turn when Glenn asked about how trustworthy Trump could be with his promises.

The caller gave a disturbing ultimatum.

“As long as he does the basic things, the foundational things, which is build a wall, he’s not going to have people like me coming after him,” Nate said.

Watch the clip from The Glenn Beck Program:

Glenn sought clarification.

“Okay. So if he doesn’t build a wall like China, then he’s in trouble,” Glenn said. “It’s the wall that is your line?”

The caller’s reply was dangerously threatening.

“Oh, he’s in so much trouble,” he said. “You don’t even understand the backlash of us, the ones who are so frustrated and angry and tired of all the political stuff. We’re going to come after him personally. You know what I mean? We’re going to get him.”

Glenn gave the caller every opportunity to clarify what he was saying.

“I don’t know what you mean,” Glenn said. “Hang on. What does that mean?”

He must have meant impeachment, right? Yes, but it didn’t stop there. Apparently, violence wasn’t out of the question for Nate.

“Well, I mean, hey, you yourself said he’s condoned violence in the past, hasn’t he?” came Nate’s reply.

Glenn couldn’t hide his shock at what he was hearing. The caller went on with a chilling threat:

I’m just saying, he’s appealing to people who are very frustrated and angry. Their frustration and anger can only be subsided if he makes his promises true. And he has a lot on his shoulders. Maybe he himself doesn’t even know how much. But if he doesn’t come through for us, he’s going to have bigger problems, bigger problems than what you know.

That was enough to make Glenn declare this the “spookiest” phone call he’d ever received.
