After the government had been shut down for nearly a month, a conspicuously quiet President Donald Trump finally weighed in with a prescription for how to end it.

Republican congressional leaders are probably wishing he hadn’t.

Trump late Thursday night urged Republicans to end the shutdown by invoking the so-called “nuclear option” — that is, getting rid of the filibuster and 60-vote threshold in the Senate. This would allow Republicans to pass things on party-line votes in the GOP-controlled Senate.
