The House on Saturday unanimously approved legislation to provide retroactive pay for furloughed federal workers after the government shutdown ends. The vote was 407-0.

The White House said Friday that it “strongly supports” the legislation and urged its “swift” passage, even while warning that the single bill alone “will not address the serious consequences of the funding lapse.” The Senate could take it up as soon as today.

Approximately 800,000 government employees are furloughed during the shutdown.

Workers deemed essential and who are currently on the job will be paid for their work during the shutdown, although their paychecks could be delayed. But furloughed employees need congressional approval to receive back pay.
