Senators Susan Collins (R., Maine) and Mitt Romney (R., Utah) will not support Neera Tanden’s nomination for director of the Office of Management and Budget, further endangering the confirmation of President Biden’s nominee.

“Congress has to be able to trust the OMB director to make countless decisions in an impartial manner, carrying out the letter of the law and congressional intent,” Collins said in a statement on Monday. “Neera Tanden has neither the experience nor the temperament to lead this critical agency.”
