Yesterday, CNN sent shockwaves through the political Twittersphere when it reported that special counsel Robert Mueller—the man charged by the Justice Department with investigating alleged Russian interference in the 2016 U.S. presidential election—had gotten a federal grand jury to approve charges against at least one as-yet unnamed person. The news was met with a certain amount of glee from people hoping Mueller will be going after someone in Donald Trump’s inner circle, and a lot of speculation about how Trump and his various advisers and assorted hench-persons will respond to what now looks like a ticking clock over somebody’s head. (According to CNN, an arrest could be made as early as Monday.)
