We've known about the move since late last year, but ABC News president Ben Sherwood finally made it official Today in a memo to the staff.

Shrewood told the staff in an internal memo that ABC Mara Schiavocampo has joined ABC News as a New York-based correspondent.

Schiavocampo, who’d been with NBC since 2007 is jumping over to ABC News. 

Here's  Sherwood’s memo to staff:

Mara is a dynamic storyteller and skilled journalist who has covered nearly every major news story in the past decade.  During the manhunt for the Boston Marathon bombers, Mara anchored for five straight hours as news broke that suspect Tamerlan Tsarnaev was killed during a shootout with Watertown police.

Mara’s reporting has been recognized with several honors, including an Emmy for her coverage of the 2008 Presidential Election.  In 2007, she was the only broadcast journalist to receive the National Association of Black Journalists’ “Emerging Journalist of the Year” Award.

Mara got her start in journalism right here at ABC News as a desk assistant for Radio in 2001 and as a producer for “ABC News Now” in 2004.

Please join me in giving Mara a warm welcome back to ABC News.
