Shortly after the United States established a no fly zone over Libya, libertarian attorney Bruce Fein drew up articles of impeachment against the president.

Today:

The Ron Paul 2012 Presidential Campaign announced today that constitutional and international law expert Bruce Fein will join the campaign as senior advisor on legal matters.

This isn't actually a surprise hire, because Fein helped out Paul in 2012. Here's his speech from Paul's 2008 rally that was cross-programmed against the Republican National Convention. But Fein's more prominent now, and his obsession -- the constitutionality of wars -- is one Republican primary voters are more interested in now that George W. Bush isn't president.
