While it isn't actually a surprise to most of us (that is, we knew it) that the conservative military Democrat from rural PA probably isn't on Barbra Streisand's rolodex, contra Aravosis and bogus email publisher Zengerle thus far there has been no confirmation that Murtha tried to discourage Keller from publishing the SWIFT story. As Media Matters explains, while Murtha was one of the people Keller says the Times talked to, Keller also asserts that not all of them tried to discourage them from publishing the report.
I don't especially care either way, but those are the facts.
