POTUS. You are watching a movie.
CS = Chuck Schumer
but Grassley doesn't get back to Judiciary till January of 2021. Seems as if Graham was put in charge of Judiciary just for this process. He is a former prosecutor, I believe.
when the announcement was made, he said next Congress. That would be after the 2020 election, so January 2021.
this article explains the back and forth pretty well.
