So … just how toxic is the relationship between Donald Trump and the nation’s civil rights leadership?

Get a load of this: U.S. Rep. John Lewis, D-Ga., arguably the greatest living leader of the civil rights movement, plans to boycott the opening of a civil rights museum in Mississippi because the president of the United States will be there.

The ceremony will occur Saturday.

I am torn on this one. Lewis’s statement talks about the inflammatory rhetoric the president has uttered since taking office. He has taken extreme offense at Trump’s statements about race relations, not to mention his terrible initial response to the Charlottesville, Va., riot spawned by the presence of white supremacists, Nazis and Ku Klux Klansmen.

The president’s participation in the museum dedication, though, is noteworthy. If only he hadn’t built up a disgraceful record of clumsy statements that many have interpreted as being overtly racist.

That’s the kind of history, according to Rep. Lewis, that the president cannot erase with a simple public appearance.
