Congressional Republican leader Marjorie Taylor Greene backs “national divorce.” (MSNBC / Steve Benen)

In a President’s Day tweet, Greene endorses breaking up the United States. Then she walks it back and says she’ll settle for impeaching Joe Biden—but if that doesn’t happen, the US has to go, she says.

Elected political leaders should support the United States continuing to exist. That’s a pretty low bar. But the Republican Party can’t clear it.
