After Republican presidential candidate Donald Trump threatened to skip CNN’s town hall, his rival, Texas Sen. Ted Cruz, issued a challenge to debate him instead.

CNN is scheduled to host a town hall with all three remaining GOP presidential candidates Tuesday evening, but Tuesday morning, Trump tweeted, “Maybe I shouldn't do their town-hall tonight!”

During a campaign stop in Wisconsin, Cruz responded by saying, “Our friend Donald finds debates very, very stressful,” according to The Hill.

"They make his hair stand on end," Cruz added.

Cruz called for Trump to debate him.

"We’re in the same location,” Cruz said. “They got the TV cameras, they got the moderators ... the one thing they’re missing is The Donald.”

“Donald prefers to communicate in 140 characters or less,” he added.

Cruz has repeatedly called for Trump to debate him, and Trump mocked Cruz on Twitter about it Monday evening.

"It’s neck and neck,” Cruz said. “Donald Trump and I are effectively tied in the state of Wisconsin. That means ... any candidate running for president owes it to come in front of the state and actually debate."
