Arizona Attorney General Kris Mayes said Friday that her office is investigating whether former President Donald Trump's violent comments about former Republican Rep. Liz Cheney violated the law.

“I have already asked my criminal division chief to begin reviewing this statement and analyzing it to determine whether it qualifies as a death threat under Arizona law,” Mayes, a Democrat, said during a recording of “Sunday Square Off.” 12NEWS in Phoenix.

“I'm not ready to say now whether it was or not, but it's not helpful as we prepare for our election and try to make sure we keep the peace in our polling places and in our state. Mayes told the NBC affiliate.

A spokesman for the attorney general's office, Richie Taylor, confirmed to NBC News that the office is “reviewing” whether Trump's comments violated Arizona law. NBC News has reached out to the Trump campaign for comment.

At an event with Tucker Carlson in Arizona on Thursday, Trump suggested that Cheney wouldn't be such a “war hawk” if she had guns “pointed at her face.”

“She is a radical war hawk. “Let’s put them there with a nine-barreled gun,” Trump said. “Okay, let’s see what she thinks. You know, when the guns are pointed at their faces – you know, they're all warmongers sitting in a nice building in Washington.

In a post on his Truth Social account Friday afternoon, Trump said that Cheney “didn't have the courage to fight herself.” She finds it easy to talk when she's sitting far from the death scenes, but when given one If you pick up a gun and let her fight, she'll say, 'No thanks!'” In remarks to reporters later on Friday, Trump defended his comments about Cheney by again calling her a war hawk and saying that “they are people kills”.

Earlier in the day, Trump campaign spokeswoman Karoline Leavitt said Trump was “100% right that warmongers like Liz Cheney are quick to start wars and send other Americans to fight them rather than go into battle themselves.”

Trump escalated his violent rhetoric on the campaign trail last month. He called Democrats and his opponents an “enemy from within” and vowed to use the U.S. military against American citizens. He has also said during the 2024 race that he could throw his political opponents in prison.

Vice President Kamala Harris said Friday that former President Trump's comments about Cheney should be “disqualifying.”

“He has stepped up his violent rhetoric like Donald Trump toward political opponents and suggested in great detail that guns should be pointed at former Rep. Liz Cheney,” Harris told reporters after landing near Madison, Wisconsin.

“That has to be disqualifying. “Anyone who wants to be president of the United States and uses this type of violent rhetoric is clearly disqualified and unfit to be president,” she added.

Harris said that Trump is “permanently bent on revenge” and that he is “increasingly unstable and unhinged.” “His list of enemies has grown longer, his rhetoric has become more extreme, and he is even less focused than before on the needs, concerns and challenges facing the American people,” she said.

When asked for comment on Harris' comments, Leavitt reiterated his statement from earlier in the day.
