Charles Krauthammer “worr[ies] for the country” after news breaks of Special Counsel Robert Mueller’s new grand jury. That, he said on Fox News, along with the bills introduced in the Senate to protect Mueller from being fired, could bring President Trump, Congress, and the Supreme Court into conflict. Krauthammer explains:

Tonight’s news is not just a threat to Trump and his entourage but it is [a threat] to constitutional stability. The president has said that he’s got a red line. If they want to go on a fishing expedition that is unrelated, essentially, to the Russia probe, that’s where he draws a line. Now, he didn’t say what he would do but you know what he would have in mind.
