After more than two years at National Journal as chief analyst, deputy daily briefings editor and White House correspondent, Jim O’Sullivan is returning to Massachusetts to fill the Political Intelligence post held until recently by Glen Johnson, who left the paper to work for Secretary of State John Kerry.

O’Sullivan plans to start on or before March 11, according to a memo from deputy managing editor for local news Jen Peter, a former Associated Press reporter who, like O’Sullivan, also spent a solid stint reporting out of the State House.

“For Jim, this will be a homecoming. He grew up in Cohasset, graduated from Boston College, and worked at the Dorchester Reporter and State House News Service, before heading down to Washington three years ago. At State House News, he covered it all – the health care law, gay marriage, Patrick, Romney, leadership battles, budgets, etc – and broke just enough stories to irritate the Globe,” Peter wrote.
