Seventy members of Congress have signed a letter to Environmental Protection Agency Administrator Scott Pruitt expressing concerns over the recent dismissal of several members of the Board of Scientific Counselors. Earlier this month, Pruitt decided to replace half of the people on the 18-member board, which weighs in on the integrity of the administration’s scientific research.

The letter, which urges Pruitt to maintain the credibility of the board and not appoint new members with conflicts of interest, is primarily signed by House Democrats. Upstate Republican Elise Stefanik is one of three GOP members to sign on though.

“It’s critical that the EPA continues to use the highest quality research when making policy decisions, and the recent dismissal of these members of the Board of Scientific Counselors is very concerning,” Stefanik said. “As the proud Representative of the Adirondacks, we rely on the important work being done by the EPA to protect our nation’s ecological treasures, and I urge Administrator Pruitt to maintain the highest scientific standards at this important agency.”

Two Florida Republicans, Rep. Carlos Cubelo and Rep. Ileana Ros-Lehtinen, also signed the letter. Upstate Democrat Louise Slaughter participated as well.

“I’m deeply concerned that this board will now be stocked with industry representatives who will rubber stamp the president’s anti-environmental agenda,” Slaughter said. “This speaks volumes about the Trump Administration’s complete disregard for science and facts. It is beyond me how Republicans in Congress could claim to care about our environment while supporting a president who doubts the proven science of climate change.”
