Story highlights "I do believe the president is mentally unstable," Gallego said. (CNN) Arizona Rep. Ruben Gallego said Friday that he thinks President Donald Trump is "mentally unstable." "Yes, I do believe the president is mentally unstable," Gallego, a Democrat, said on KTAR News 92.3 FM's Mac & Gaydos . Gallego made similar comments on CNN in August when Trump was the Republican nominee, arguing at the time that, "this man is unstable, he's unfit to be a presidential candidate." "I will not work with President Trump because President Trump has not been clear and transparent with what occurred during this election," Gallego said.
