AUSTIN (Nexstar) — Governor Greg Abbott says he is accepting an invitation for a debate, hosted and broadcast by Nexstar Media Group which is the parent company of KXAN.

Challenger Beto O’Rourke has not yet confirmed whether he will participate, but in return, challenged Gov. Abbott to three town-hall style debates.

If they both agree on a time and date, the candidates will debate on the campus of the University of Texas-Rio Grande Valley in Edinburg.

KXAN will broadcast the debate, along with other Nexstar stations across Texas.

There are other candidates on the ballot for governor – but this debate will focus on Abbott and O’Rourke.

Nexstar Media adopted a set of criteria to determine which candidates are eligible to participate in a debate, which includes a requirement that a candidate must receive at least 10% support in an established, professionally-conducted, non-partisan poll leading up to the election.

A candidate also must have raised at least $50,000 in campaign contributions to be eligible.
