Former House Speaker Newt Gingrich (R-Ga.) said Tuesday that he regrets making a commercial with then-Speaker Nancy Pelosi (D-Calif.) on the need to address climate change.

Gingrich, who partnered with Pelosi while she was Speaker for the 2008 ad, said the spot was "misconstrued," and for that reason, he wouldn't do it again.

"I was trying to make a point that we shouldn't be afraid to debate the left, even on the environment," Gingrich said on WGIR radio of the 30-second television commercial. "Obviously it was misconstrued, and it's probably one of those things I wouldn't do again."

That commercial has caused some difficulties for Gingrich in the Republican presidential primary. Pelosi is one of the most polarizing figures for primary voters, and the appearance of wanting to partner with such a political bogeyman has arguably hurt Gingrich with GOP voters.

Gingrich said in January that he "meant exactly what [he] said in that commercial," which was produced by the Alliance for Climate Protection, a nonprofit organization founded by former Vice President Al GoreAl GoreOvernight Tech: Trump's tech budget - Cyber gets boost; cuts for NASA climate programs | FTC faces changes under Trump | Trump to meet with Bill Gates Trump's NASA budget cuts earth, climate science programs Obamas sign with agency for speaking gigs MORE (D). In the ad, Gingrich makes no endorsement of any policy solution, but says the "country must take action to address climate change."

But Gingrich has also made some environmental issues a part of his presidential campaign, calling for the elimination of the Environmental Protection Agency (EPA) and its replacement with an agency dedicated to energy creation.
