New Romney Ad Focuses on Gingrich's Ethics Violation January 26, 2012, 10:33 am JACKSONVILLE, Fla. - Moving on to Phase 2 of its aggressive campaign to stop Newt Gingrich's momentum before the primary here on Tuesday, former Gov. Mitt Romney of Massachusetts is beginning to show a new, bruising advertisement focusing on the Congressional ethics finding against Mr. Gingrich in the 1990s. More specifically, it raises the specter that the former House speaker, Nancy Pelosi, Democrat of California, who was on the investigative committee that looked into Mr. Gingrich at the time, is holding back a secret dossier of damaging information that she will presumably share if he becomes the Republican nominee. Several weeks ago Ms. Pelosi told Talking Points Memo that she knew "a lot about"" Mr. Gingrich from being one of four people who were "locked in a room in an undisclosed location" going through "a thousand pages of his stuff." More recently she told John King of CNN that she was certain Mr. Gingrich would not become president because "there is something I know." But her office said she was referring to publicly available records relating to the ethics investigation, which found that Mr. Gingrich had used a college course he was teaching - and soliciting donations for - as a way to forward partisan aims. Mr. Gingrich was fined $300,000 for the costs of the investigation and admitted he had engaged in conduct that did not reflect well on the House. The ad will run on broadcast television in select markets in Florida.
