Ted Cruz on Friday said he will debate Beto O'Rourke, though he didn't specify the time of the showdown or how many should occur.

"Oh, sure. We will debate," Cruz said during an appearance on Lone Star Politics, a political show produced by KXAS-TV (NBC5) and The Dallas Morning News. "As you know, I am not remotely concerned or afraid to debate far-left Democrats."

O'Rourke didn't comment on Cruz's remarks. In March the junior senator said he would debate O'Rourke, but no official agreement has been reached.

For his 2012 campaign, Cruz had a high-profile debate with former Lt. Gov. David Dewhurst in their GOP primary race for Senate. And when some aides advised him against it, he debated former state Rep. Paul Sadler in the general election for Senate.

"It was the right thing to do," Cruz said after recording the show.

Cruz also had numerous televised debates during his 2016 Republican bid for president.

He said he looks forward to discussing policy with O'Rourke.

"His campaign, by running so far left, doesn't reflect who we are," Cruz said. "The contrast of ideas is important and that's the way I've always tried to approach the political world."

O'Rourke, an El Paso congressman, has challenged the incumbent Republican to six debates, including two in Spanish.

It's unlikely that Cruz will agree to debate six times. That many debates would be unusual in modern Texas politics.

On Thursday, the O'Rourke campaign and Texas Democrats needled Cruz for not officially responding to a letter O'Rourke's camp sent in April requesting a series of debates. In response, Cruz spokeswoman Catherine Frazier told The News in an email: "We'll debate of course, but we aren't beholden to any made-up timelines."

O'Rourke, with his stout fundraising and aggressive campaigning, has given Democrats hope that he can deliver the party's first statewide win since 1994.

He was campaigning in Dallas Friday, telling Democrats that it was important to reach out to Republicans and independents.

Cruz acknowledges that O'Rourke is a formidable candidate, though he said the El Paso congressman's campaign is fueled by anger Democrats have over President Donald Trump and losing the 2016 election.

And he conceded that O'Rourke would continue to raise more campaign cash than him. In the first quarter of this year O'Rourke raised $6.8 million, more than twice what Cruz raised.

But the incumbent said there are far more voting conservatives in Texas than Democrats, and that O'Rourke's polices — including raising taxes, expanding the Affordable Care Act, gun control, sanctuary cities and supporting the idea of impeaching Trump were too extreme for most Texans.

"Those are views that appeal to the extreme left," Cruz said. "That doesn't reflect the common-sense views of Texas."

Lone Star Politics airs Sunday at 8:30 a.m. on NBC5.
