President Donald Trump has lost a long-time talent because of his "cognitive decline," one of his family members said. During an episode of Fast Politics, host Molly Jong-Fast spoke with Mary Trump, who is the president's niece, a psychologist, and a frequent critic. "Donald did have the ability to read the room better," Mary Trump said. What that means is he's losing impulse control," Mary Trump said. "You've got this very old man who's clearly not doing well in every category of being human, psychologically, emotionally, cognitively, physically," Mary Trump said.
