'Deeply unhealthy': Trump's niece ties his growing 'feebleness' to weakening hold on GOP

Donald Trump's increasingly failing cognitive capabilities are causing Republican lawmakers to depart from the president more often, according to a member of the Trump family.

Mary Trump, the niece of the president and a trained psychologist, on Saturday published a video in which she talks about her uncle's "crumbling" hold over Republicans.

"Concerns over Donald's physical and mental decline are mounting even among Republicans," she said. "Donald is 79 years old and a deeply unhealthy person. His father had a very serious case of Alzheimer's that went on 15 years."

Mary Trump went on to say, "Every day, Donald seems increasingly feeble and unable to focus. Even the New York Times is starting to catch on to this. As he weakens, so too does his hold over the Republican party."

Mary Trump further mentions previous reporting that Trump's MRI results caused some GOP lawmakers to stand up to him, as well as reporting that the president accidentally boosted a post calling for him to be impeached.

"In other words, Donald promoted words calling for him to be removed from office," she said, noting that her uncle can no longer tell "his days from his nights."
