In this March 11, 1989, photo Donald Trump shakes hands with former President Richard Nixon at a tribute gala to Nellie Connally at the Westin Galleria ballroom in Houston, Texas. The letters between Trump and Nixon revealed for the first time in an exhibit that opens Thursday, Sept. 24, 2020, at the Richard Nixon Presidential Library & Museum, show the two men engaged in something of an exercise in mutual affirmation. The museum shared the letters exclusively with The Associated Press ahead of the exhibit’s opening. (Richard Carson/Houston Chronicle via AP)
