Republican presidential hopeful Ted Cruz on Tuesday challenged 2016 rival Donald Trump to a one-on-one debate after the real estate mogul announced he would skip the debate hosted by Fox News later this week.

Cruz made the challenge during an appearance on conservative radio host Mark Levin’s show.

The Texas senator offered two choices: he could debate Trump for 90 minutes without a moderator or the billionaire could select an individual to host the debate.

“We could do it a number of ways, we could have you moderate it, Mark. We could have Sean Hannity moderate it. We could have Rush Limbaugh,” Cruz said.

He continued, “But you know what? If he’s afraid of Megyn Kelly, if he’s afraid of you, and afraid of Hannity, and afraid of Rush, then we could do without any moderators whatsoever. I’m happy to go an hour-and-half mano a mano me and Donald with no moderators anytime before the Iowa caucuses.”
