Dr. Jonathan Reiner said he was “seriously concerned” about Donald Trump's health after watching the president's speech, following a column by Moira Donegan that catalogued signs of physical decline and a New York Times analysis showing roughly a 40 percent drop in Trump's public appearances since his first year in office.Reiner, who treated Dick Cheney, criticized Trump's tone and "manic" delivery, renewed questions about an MRI in October and persistent bruising and swollen ankles that the White House has attributed to chronic venous insufficiency, while Trump insists he "aced" a cognitive test and has attacked the Times' coverage.
