Former U.S. House Speaker Newt Gingrich rebuked House Minority Leader Nancy Pelosi for suggesting she would offer details of a 1990s ethics probe against him if he becomes the Republican presidential nominee.

Gingrich, who was reprimanded by the House in 1997 after an ethics investigation, said members of Congress should bring charges against Pelosi, herself a former speaker, if she follows through on airing aspects of the probe.

“I want to thank Speaker Pelosi for what I regard as an early Christmas gift,” said Gingrich, taking questions from reporters in New York after meeting yesterday with real estate developer Donald Trump. “It tells you how capriciously political that committee was that she was on it. It tells you how tainted the outcome was that she was on it.”
