WaPo:

Former House speaker Newt Gingrich will not face a Federal Election Commission investigation into allegations that he broke federal law by using his 2012 presidential campaign to promote books that he and his wife wrote, documents released Friday show.

As part of an agreement with the FEC finalized Feb. 23, the veteran Republican party leader will shut down his 2012 committee, Newt 2012, in the next few months. The campaign still owes nearly $4 million to more than 100 vendors, who are now unlikely to see full payment.

The FEC’s top attorney recommended in 2013 that the agency investigate Gingrich, but the case languished and the six-member commission eventually deadlocked along partisan lines in June, with the three Republican commissioners voting against an inquiry.
