WASHINGTON (JTA) — The U.S. government returned to work, and officials who track Iran sanctions compliance were working at a full complement.

Hundreds of thousands of government employees who had been furloughed since Oct. 1 returned to work on Thursday after Republicans in the House of Representatives agreed to pass a funding bill advanced by the Democratic-led Senate the previous night.

A spokesman at the U.S. Treasury confirmed that the employees included officials of its Office of Foreign Assets Control, the office responsible for monitoring international compliance with U.S. sanctions targeting Iran for its suspected nuclear weapons program.

Obama administration officials had said the shutdown was having an impact on sanctions compliance, and suggested that it could cost the United States leverage as it leads negotiations renewed this month between the major powers and Iran on its nuclear program.

The deal ratified in the Senate and House did not meet demands by House Republicans that any extension on funding government spending should be tied to undoing parts or all of President Obama’s 2010 health care reforms.
