text: DonAlt tRump has cancelled out of a planned visit to the African American Museum in D.C. That was planned for Martin Luther King Day on Monday. His team sites  conflicting arrangements but after his now famous dressing down of Mr. Lewis, it is undoubtedly because he fears being booed and jeered at by the other visitors.
