I’m saying that Trump’s allies control the House and the Senate, and they have already bent over backward to avoid investigating this matter, so it’s abundantly clear what they’d do if he fired Mueller (same thing as when he fired Comey–either nothing at all, talk about how Mueller was a liberal partisan hack, or the McCain Special*). The courts have no legal authority to investigate, prosecute, or remove a President, so it doesn’t matter where they stand.
* Talk about what a sad, bad, terrible thing this is. Outrageous, unwarranted, and unprecedented. And then do nothing.
