Being on Nancy Pelosi’s enemies list is not necessarily a bad thing, as Newt Gingrich made clear Monday when he thanked the House minority leader for the “early Christmas gift” of criticizing him.

Pelosi, in an interview with Talking Points Memo, echoed Rep. Barney Frank (D-Mass.) in saying “I never thought I’d live such a good life that I would see Newt Gingrich be the nominee of the Republican Party.”

““I know a lot about him,” Pelosi said in the interview. “I served on the investigative committee that investigated him, four of us locked in a room in an undisclosed location for a year. A thousand pages of his stuff.”

Pelosi was referring to the 1997 House reprimand of Gingrich after House ethics committee probe into his useof tax-deductible money for political purposes.

But the former House speaker quickly responded to what he believed to be an implicit Pelosi threat, saying any such disclosure of private ethics committee materials would be “a fundamental violation of the rules of the House.” He added: “What she says today should explain a great deal about what happened to the ethics process when Nancy Pelosi was at the helm.”

Gingrich said that the House should “immediately condemn her if she uses any material that was gathered when she was on the Ethics Committee.”

Gingrich was speaking to reporters in New York following a meeting with businessman Donald Trump, whom Gingrich persuaded to consider creating a number of part-time apprenticeships for children as young as age 10 modeled on Trump’s popular TV show.

Gingrich’s idea is to create paying opportunities for underprivileged children to teach them the value of hard work and a paycheck, he said.

The idea was a riff on Gingrich’s common mode of comparing himself to President Obama. Obama, Gingrich likes to say, is the greatest “food stamps” president in American history, while Gingrich plans to be a “paycheck” president.

“When you have 43 percent black teenage unemployment, there’s a very serious challenge in getting people to understand the work ethic,” Gingrich said.
