Labor Department officials are still hopeful that they can release the report as scheduled at 8:30 a.m. Friday. But they acknowledged Monday that the storm could cause a delay.

“Our intention is that Friday will be business as usual regarding the October employment … report,” said Jennifer Kaplan, a department spokeswoman.

Preparation for the jobs report typically ramps up in the week of the release. The federal government was closed Monday and final calculations could be delayed if the government stays shuttered because of the storm.

Tom Nardone, who oversees the preparation of the report, said some advance work was done Friday. And some employees were able to work remotely on the report Monday.

But the jobs report is usually subject to strict security measures so it is unlikely that much work can be done when the government is closed.

The report is scheduled to be released four days before Election Day.

The unemployment rate fell in September to 7.8 percent. That marked the first time that the rate had dropped below 8 percent since January 2009 — President Barack Obama’s first month in office.

A delay in the reporting of the October employment figures — days before voters go to the polls — could spark more of the political controversy that first surfaced after the September report was released.

Former GE chief executive Jack Welch tweeted that the job numbers were “unbelievable” and suggested they had been manipulated. Republican Rep. Allen West of Florida later announced on Facebook that he agreed with Welch.

That suggestion was roundly rejected by economists and former officials at the Bureau of Labor Statistics, which issues the report. Democrats and even some Republicans said they also found the charges implausible.
