A bit of esoteric history courtesy of Justice Ginsburg, writing in "My Own Words":

Judge Lurton served on the US Court of Appeals for the Sixth Circuit and was appointed to the Supreme Court seven years later in 1909, serving his first two years on the Court together with Justice John Marshall Harlan.

Both justices served in the Civil War...

...on opposing sides.

Judge Lurton served on the Confederate side. Justice Harlan fought for The Union.

They were fast friends afterward.

Never let politics get between you and your friends/family. Political events are temporary. Relationships are longer-lasting.
