Sitting down with Tucker Carlson in Arizona late Thursday, Trump unleashed on former Rep. Liz Cheney.
"She's a radical war hawk," Trump said as he accused her and her father, former Vice President Dick Cheney, of leading the United States into the war in the Middle East.
"Let's put her with a rifle standing there with nine barrels shooting at her," Trump said, invoking violence on his opponents as he implied that she sends people to war without having any war experience of her own.
"Okay, let's see how she feels about it. You know, when the guns are trained on her face. You know, they're all war hawks when they're sitting in Washington in a nice building saying, 'Oh, gee, Will, let's send a, let's send 10,000 troops right into the mouth of the enemy,'" Trump continued.
He also repeatedly called Cheney a "stupid" and "bad" person.
