Former President Donald Trump's call for a cease-fire in the Russia-Ukraine war and negotiations toward a truce has differed from the stance of some of his supporters and many Republicans.
Most GOP members have strongly supported Ukraine since Russian President Vladimir Putin began his country's unprovoked attack in February.
Trump has criticized the Biden administration's handling of the conflict.
"With potentially hundreds of thousands of people dying, we must demand the immediate negotiation of the peaceful end to the war in Ukraine, or we will end up in World War III and there will be nothing left of our planet all because stupid people didn't have a clue," Trump told supporters Saturday at a rally in Arizona.
"They really don't understand … what they're dealing with. The power of nuclear. They have no idea what they're doing."
