The Washington Post put three researchers on a story and travelled to Arizona to cover an anti-John McCain story at the request of a left-wing group’s staffer who is now Hillary Clinton’s deputy communications director, a leaked email exchange reveals.

In March 2008, Washington Post staff writer Matthew Mosk, now at ABC News, wrote, “McCain Pushed Land Swap That Benefits Backer.” The story Mosk wrote centered on the idea that Sen. McCain has helped out land developers who have donated money to him.

The same day the story was published, Tara McGuinness, formerly with the Center for American Progress and now senior adviser at the White House’s Office of Management and Budget, wrote to several Obama and Clinton allies, “Christina Reynolds single handedly convinced Mosk to put 3 researchers on this and to go to Arizona himself.”

Reynolds at the time was deputy campaign manager for Progressive Accountability, a project that was ran jointly by John Podesta’s Center for American Progress and David Brock’s Media Matters. Reynolds shortly thereafter joined President Barack Obama’s campaign and then worked in his administration. She is now deputy communications director for Hillary Clinton’s campaign.

In response to McGuinness’s email, Paul Begala, former counselor to President Bill Clinton and currently a senior adviser to a pro-Hillary Super PAC, said, “This is truly outstanding! Great work!”

The email exchange was included in the Wikileaks release of thousands of John Podesta’s emails. He was included on the email chain, as was David Brock.

The Daily Caller has reported on how the recent Wikileaks release has exposed journalists from a variety of major organizations who are in Clinton’s corner.
