Republicans have blocked yet another of President Obama’s judicial nominees with a Senate filibuster. Georgetown Law Professor Nina Pillard would have been just the sixth woman to serve on the U.S. Court of Appeals for the District of Columbia. She is also the third-straight female nominee blocked by Republicans. During debate, Republicans cited past comments from Pillard arguing that reproductive rights strengthen gender equality. Several Democrats say the move could prompt a new showdown over Senate filibuster rules.
