In the run-up to the run-off elections Aug. 28, the race for the GOP spot has become a fight over who is more conservative; Kevin Stitt or Mick Cornett. In recent ads attacking Cornett, the Stitt campaign goes after statements he’s made about immigration and President Donald Trump.

Mayor Cornett didn't back Donald Trump for President,” The ad alleges. “Mayor Cornett is not just a “never-Trumper”, Mayor Cornett defended sanctuary cities and said building President Trump's border wall ain't going to get us anywhere. He actually said that.”

So is this ad telling the truth? Mostly. Let's take the first claim. Did Cornett decide not to endorse the President? Yeah, but he didn't back anyone else either which he said in the full interview.

“I have not endorsed Donald Trump or any other candidate in this race,” Cornett said on MSNBC’s Meet the Press Daily in October before the election. “Yeah normally I have. This is an unusual case with a candidate who's said some outrageous things…just as open-minded as I have remained I have just not seen a way to endorse him and the strategies that he's used in the campaign. I don't think they're helpful for America.”

So what about the border wall? Let's look.

The ad is taking quotes from USA today here Cornett does say the border wall "isn't going to get us anywhere". The attack ad says ain't instead of isn't but the idea is still the same.

And on sanctuary cities the ad is downright false.

What Cornett actually said was the term sanctuary city was a political term, not a legal one, saying during an interview at the Conference of Mayors in 2017, "To me that's the only end result of that term. It's not a term that we understand or use,” he said.

So how does this attack do? On its three claims we'll give it two truths and a false.
