See http://blogs.wsj.com/washwire/2013/06/07/transcript-what-oba...; for the full answer to the question. Obama separately addresses the phone issue and the internet issue. In both cases he implicitly admits that what was said in the press about them is substantively true. In both cases he claims that Congress and the FISA court were kept appraised. In both cases he defends the programs with justifications that can be supported by what was said about them in the press. He makes it clear that they are separate programs.

The inevitable conclusion is that while he did not specifically confirm what was said in the press, he lent great credibility to the leaks being real documents describing real programs.
