DES MOINES, Iowa — Newt Gingrich has taken heat on the campaign trail from conservatives for filming a 2008 commercial on climate change with House Democratic leader Nancy Pelosi.
But that was hardly the first time the Republican presidential candidate and former House speaker collaborated with Pelosi.
Gingrich co-sponsored 418 bills in Congress with Pelosi during the 12 years they served together in the House, according to the Library of Congress’s THOMAS database.
Gingrich was in Congress from 1979 to 1999. Pelosi has served since 1987.
As a matter of comparison, House Speaker John Boehner, who has served in Congress with Pelosi for more than 20 years, has only co-sponsored 104 bills with her.
Many of the bills Gingrich and Pelosi co-sponsored were hardly divisive: authorizing an award for Mother Teresa, giving a congressional gold medal to former President Gerald Ford and recognizing the 50th anniversary of the National Heart, Lung, and Blood Institute.
But one piece of legislation could be problematic for Gingrich with conservatives: the Global Warming Prevention Act of 1989, which never made it out of committee.
