Longtime Washington Post reporter Bob Woodward is taking on the White House, saying in multiple interviews that the administration essentially threatened him to try to get him not to write a story.

Politico has an interview with Woodward and his correspondence with top Obama economic adviser Gene Sperling, in which Sperling apologizes for raising his voice at Woodward in a phone call but then proceeds to say Woodward would "regret" it if he pursued his story -- about whether Obama had moved the goalposts on the sequester.

"But I do truly believe you should rethink your comment about saying that Potus asking for revenues is moving the goal post," Sperling said in the e-mail obtained by Politico. "I know you may not believe this, but as a friend, I think you will regret staking out that claim."
