Bill Clinton — who had worked for a challenger's 1974 campaign — before the U.S. Senate during his impeachment trial.

That sounds quite a bit like a line from Hillary Clinton's victory speech on Tuesday, in which she said, ""We believe that cooperation is better than conflict, unity is better than division, empowerment is better than resentment, and bridges are better than walls."
Trump of course has infamously promised to build a wall on the border between the United States and Mexico should he get elected in November.
Whether or not the remark was intended to be about Trump, Crystal delivered an equally touching and hilarious eulogy for Ali.
Crystal recounted how he first met Ali in 1974, when his stand up act included doing an impression of both Howard Cosell and Ali. Ali loved the routine, and called Crystal his "little brother" from then on.
