On Wednesday evening, the Cruz campaign announced that that they were making Cruz’s challenge to Trump official, in that they sent Trump a letter of invitation to debate on Saturday.
As you can see in the letter below, Cruz has already secured the venue and time.
January 27, 2016
We owe it to the men and women of Iowa to ensure that they hear jointly and directly from the two leading Republican candidates so that they may contrast our positions on the critical issues we face as a nation as they make their final choice leading up to Monday’s caucuses.
Accordingly, please accept this invitation to join me at an in-person, two-hour Town Hall event at Western Iowa Tech Community College in Sioux City this Saturday, January 30th at 8:00 p.m. Central. This venue is already reserved and I would propose that our campaigns evenly divide available seating/ticketing. Our teams can jointly work on the logistical details.
Additionally, I propose one of the following three individuals serve as a Town Hall facilitator: Mark Levin, Sean Hannity or Rush Limbaugh. If none of these proposed individuals are acceptable to you, I suggest that instead we alternate in fielding direct questions from the audience.
I look forward to your timely response.
“If ‘Gentle Donald’ cannot handle Megyn Kelly, how about for a moderator instead, Mark Levin?” Cruz asked a crowd while on the campaign trail in Iowa on Wednesday to loud cheers of approval.
“Or if he doesn’t like Mark Levin, how about Sean Hannity? And if he doesn’t like Sean Hannity, how about Rush Limbaugh?” he asked to the increasingly fired-up audience.
A pro-Cruz Super PAC, Keep the Promise 1, ramped up the challenge, saying they will donate $1.5 million to veteran charities if Trump agrees to the debate:

On Wednesday’s Hannity, Sean Hannity told Ted Cruz that he would gladly moderate.
