Sen. Al Franken (D-Minn.) said early Sunday that Republican colleagues have expressed concern to him about President Trump's mental health.
"A few, yeah," he said on CNN's "State of the Union."
"We all have this suspicion that, you know, he lies a lot. He says things that aren't true. That's the same as lying, I guess," Franken, who's mentioned as a possible 2020 presidential candidate, added.
"You know, 3 [million] to 5 million people voted illegally," Franken said, referencing Trump's unsubstantiated claim that widespread voter fraud cost him the popular vote.
"That is not the norm for a president of the United States or actually for a human being."
