Liz Cheney has responded to Donald Trump's statement that guns should be fired at her, describing him as a “cruel, unstable man”.

Cheney, the former Republican congresswoman from Wyoming, wrote on X, formerly Twitter: “This is how dictators destroy free nations.”

“We cannot trust our country and our freedom to a small, vindictive, cruel, unstable man who wants to be a tyrant.”

Late Thursday, Trump escalated his criticism of Cheney, calling her a “war hawk” and questioning her commitment to sending troops into combat.

Speaking to former Fox News anchor Tucker Carlson in Glendale, Arizona, he said: “She is a radical war hawk. Let's put her there with the gun firing at her with nine barrels. Okay, let's see how she feels about it. Do you know?” when the guns are pointed at their faces.

He also suggested that if Cheney had his way, the US would be embroiled in conflicts in multiple countries. “If she had her way, we would be in 50 different countries,” Trump claimed.

Responding to backlash over the comments, Trump's campaign said the former president was criticizing Cheney's willingness to send American troops into combat despite not having served in the military himself.

Cheney has supported Trump's opponent Kamala Harris in the presidential election and has appeared with the Democratic candidate at three events in battleground states in recent weeks.
