Sanders to Hold Closed-Door Vote on Su as Labor Secretary

The HELP Committee is voting on Su's nomination "for the second time. Her first nomination failed and was returned to the White House after the Majority Leader declined to give her a vote on the Senate floor in the face of strong bipartisan opposition," Cassidy continued.

"It's important that we examine the many issues that have arisen" since Su's nomination hearing last year, Cassidy said, "and get an explanation over those serious concerns in her year of being an acting secretary."

Sanders denied a formal request from Cassidy to hold a public hearing on Su's nomination, Cassidy said.

Cassidy has previously complained that Su's nomination "has lasted for 176 days, the longest a cabinet-level nominee has waited for a floor vote when the same party controls the White House and the Senate."

He introduced in September the Advice and Consent Act to prevent the executive branch from circumventing Congress' constitutional duty to confirm the secretary of Labor who, he argued, does not have the votes to be confirmed.

The bill proposed to set a time limit of 210 days for Cabinet appointees to serve without Senate confirmation.
