Sen. Tom Carper, D-Delaware, was joined by eight colleagues in sending a letter to Office of Management and Budget Acting Director Mark Sandy to raise concerns and questions about President Donald Trump’s executive order to establish a “two for one” rule under which federal agencies are required to identify two existing regulations for elimination for every new regulation issued.

In the letter, the senators raise concerns that the arbitrary “two for one” limit on rulemaking impedes agencies ability to carry out the will of Congress.

“We are concerned that the president, in issuing this order, is ignoring the benefits for public health, safety and otherwise, that regulations put forward by agencies can bring to society as a whole,” the senators wrote.

“Regulations provide the public with essential protections and certainty that, among other things, help consumers feel confident that the products they buy and use every day are safe and provide businesses with the predictability needed to create and sustain jobs,” the senators continued. “If agencies are hamstrung by a top-down restrictive policy that imposes requirements to identify offsets before promulgating rules, these agencies may not be able to efficiently and effectively carry out the will of Congress.”

Sens. Richard Durbin, D-Illinois; Richard Blumenthal, D-Connecticut; Maria Cantwell, D-Washington; Jeffrey Merkley, D-Oregon; Ed Markey, D-Massachusetts; Gary Peters, D-Michigan; Chris Van Hollen, D-Maryland; and Sheldon Whitehouse, D-Rhode Island, also signed the letter.
