Neera Tanden’s nomination to lead President Biden’s White House Office of Management and Budget is in serious doubt after the two Senate committees in charge of vetting her candidacy postponed votes that would have set up a final floor vote.

The Senate Homeland Security and Senate Budget committees both delayed planned Wednesday votes on Tanden’s nomination, congressional aides told the Washington Examiner. If cleared by the panels, the president of the Center for American Progress would then be considered by the full chamber.
