Sen. Chris MurphyChristopher (Chris) Scott MurphyFlake's anti-Trump speech will make a lot of noise, but not much sense Senate campaign fundraising reports roll in Puerto Rico's children need recovery funds MORE (D-Conn.) said earlier Tuesday morning that even conservative brothers David and Charles Koch would benefit financially if the United States focused more on innovating renewable energy technology rather than relying on fossil fuels.

“This debate has been hijacked by the few people who profit off the status quo,” Murphy said on the Senate floor. “They are people who run the old line energy businesses who are clinging the status quo who are flooding this debate with millions in an effort to effect it.

“Even the Koch brothers are industrious enough to make a whole mess of money off new innovations.”

Sens. Brian Schatz (D-Hawaii) and Sheldon Whitehouse (D-R.I.) are leading an all-night Senate session to discuss the importance of climate change. More than 20 other Democrats have participated, including members of leadership. Senators have been speaking for nearly 12 hours.

Democrats have attacked the Koch brothers, who have made billions off oil, for delaying climate change legislation by threatening to run Tea Party candidates against Republicans who don’t vote their way.

But Murphy said climate change legislation would boost the U.S. economy, even for the Koch’s.
