Jamie Rubin, a former assistant to President Bill Clinton, and now a member of Hillary Clinton's campaign team, has dismissed David Trimble as a "crankpot". Mr Rubin was responding to Trimble's comments about Hillary Clinton's claim that she was "instrumental" in the bringing about peace in Northern Ireland. Lord Trimble had previously suggested that Senator Clinton's claim was "a wee bit silly". Rubin, a former spokesman for the US State Department, slurs David Trimble in an interview with MSNBC (watch here).

Samantha Power, one of Barack Obama's foreign policy advisers, was forced to resign from his campaign a few weeks ago after describing Mrs Clinton as a "monster" (in what she hoped would be an off-the-record comment). The Clinton campaign may be under some pressure to distance itself from Rubin's attack on a Nobel Peace Prize-winning politician who served for four years as Northern Ireland's First Minister.
