Boehner: Obama walked from non-existent debt ceiling deal

Earlier this evening, after breaking off debt ceiling talks with the White House, Speaker John Boehner sent a letter to his caucus that said, in part:

"A deal was never reached, and was never really close."

But during his 7:15 p.m. press conference, Speaker Boehner said the president walked away from a deal "at the last minute."

How can both of those things be true?
