As former presidents come together, Donald Trump has shunned the chummy "Presidents Club" – and the feeling seems to be mutual. The Presidents Club has at times led to former White House occupants working with each other despite past political disputes. But from vaccine promotion to disaster relief, Trump, who described himself as a "different kind of president" has avoided engaging with others who have worked in the Oval Office. And on the other end, the sentiment seems to be shared. Although previous presidents have fought with each other, Trump's outspoken disregard of other presidents is unique, especially so soon after leaving office, political analysts said. "He prides himself on his separateness," said presidential historian Kate Andersen Brower, author of "Team of Five: The Presidents Club In The Age of Trump."
