The Biden administration will take swift action to roll-back harmful Trump administration policies that will not have taken effect by inauguration day, a spokeswoman for President-elect Joe Biden's transition team says.
"The Biden-Harris White House will issue a memo to take effect afternoon Eastern Time on January 20 that will halt, or delay midnight regulations," Jen Psaki told a news conference.
Psaki gave as an example an expected Department of Labor ruling that would make it easier for companies to call their workers independent contractors and a bid to avoid minimum wage and overtime protections.
"If it takes effect, that rule will make it easier to misclassify employees as independent contractors, costing workers more than $US3.7 billion ($A4.8 billion) annually," she said.
"The memo would potentially freeze this rule and not allow it to be implemented."
Psaki also told the briefing that more Cabinet-level nominations could be expected from the Biden camp in the next week and repeated complaints of lack of co-operation with the transition team from the outgoing Trump administration.
She said lack of cooperation could delay production of a federal budget.
Key Cabinet nominations still pending from the Biden camp include those for attorney general and labour secretary.
