This is a new low, even for Mitch McConnell

There have been a lot of firsts in the Senate since Mitch McConnell took over leadership of Republicans, and none of them are good. For instance, the Kentucky senator engineered the first total blockade of a president’s Supreme Court nominee, led the minority in 100 or more filibusters per session, ended the filibuster for Supreme Court nominees, and seated a record number of candidates deemed unqualified to serve on lifetime appointments to the federal judiciary. Now McConnell is spearheading the destruction of one the most basic, sacrosanct of Senate traditions: letting the party conferences determine the composition of committees.
