In Rebuke to Cuomo, Lawmakers Balk at His Plans for M.T.A. Leadership

Sarah Feinberg’s potential role leading the nation’s largest transit system appeared uncertain a day after Gov. Andrew M. Cuomo announced it.

The future leadership of the nation’s largest transit system, including the nomination of the first woman to hold the top job, was unexpectedly cast into doubt by state lawmakers on Wednesday. Leaders of the Democratic-controlled State Senate indicated that they would not vote on a proposal by Governor Andrew M. Cuomo that would position Sarah Feinberg, a close ally of Mr. Cuomo’s, to become the Metropolitan Transportation Authority’s next chairwoman. The move was the latest rebuke of Mr. Cuomo by members of his own party as the governor tries to navigate several crises and overlapping investigations that have left him politically weakened.
