Following up on speculation from several months ago that Hardball exec producer Tammy Haddad was on her way out... Well, it's official. Our brother blog TVNewser has confirmation from MSNBC that Haddad will no longer be Chris Matthews' EP.

The story was broken by Rachel Sklar over at the Huffington Post. She has additional background on Haddad, a TV news vet who is one of the most capable hands in her field as well.

Word from MSNBC is that Chris Matthews is now serving as Hardball's 'managing editor' and that Haddad will continue to work on the network's "Super Tuesday" programming.
