Back at the time of the Clinton impeachment trial in 1999, AMC ran an old movie (ca. 1940) about the impeachment of Andrew Johnson which was very sympathetic to President Johnson. I watched part of it and noticed there appeared to be almost no black people in the movie--despite the fact that it was disagreement over how to deal with Reconstruction and the status of the recently-freed slaves that led to Johnson's impeachment.
I said AMC but on reflection I think it was Ted Turner’s network, TCM.
