Is there a single person left on Robert Mueller s  Trump-Russian collusion  team who isn t in bed with Barack Obama or Hillary Clinton?An attorney for special counsel Robert Mueller attended Hillary Clinton s election night party in New York City, The Wall Street Journal reported Friday.Andrew Weissmann s attendance at the party is one of many signs pointing to a troubling bias from the attorney. Weissmann has been described by The New York Times as Mueller s  lieutenant  and  pit bull. Conservative watchdog group Judicial Watch obtained an email Tuesday that revealed Weissmann praised former Acting Attorney General Sally Yates  defiance of Trump. I am so proud. And in awe. Thank you so much. All my deepest respects,  Weissmann wrote to Yates on Jan. 30. The email followed Yates  instruction to the DOJ not to defend an executive order banning immigration from seven nations, an act that led to her dismissal by President Trump.Weissmann is one of several Democratic donors that have been hired by Mueller, a registered Republican. The special counsel s  pit bull  donated a combined $6,600 to the presidential campaigns of Barack Obama and Hillary Clinton.The special counsel s probe has been criticized by Trump s allies, but the White House maintains Trump has no intention to fire Mueller.
