Biden to quickly address US 'crises'

Joe Biden will sign 15 executive actions after he is sworn in as US president, aides say, undoing policies put in place by outgoing President Donald Trump and making his first moves on the pandemic and climate change.

To address the "crises" of the pandemic, the economy, climate change and racial inequity, Biden will sign the executive orders and memorandums in the Oval Office on Wednesday afternoon, and ask agencies to take steps in two additional areas, incoming Press Secretary Jen Psaki said.

The actions include a mask mandate on federal property and for federal employees, and an order to establish a new White House office co-ordinating response to the coronavirus.

Biden will also begin the process of re-entering the Paris climate accord and issue a sweeping order tackling climate change, including revoking the presidential permit granted to the controversial Keystone XL oil pipeline.

Among a raft of orders addressing immigration, Biden will revoke Trump's emergency declaration that helped fund the construction of a border wall and end a travel ban on some majority-Muslim countries.

The Day One plans were just the start of a flurry of executive actions Biden would take soon after taking office, Psaki added.

"In the coming days and weeks we will be announcing additional executive actions that confront these challenges and deliver on the President-elect's promises to the American people," Psaki said.

Further actions will include revoking the ban on military service by transgender Americans, and reversing a policy that blocks US funding for programs overseas linked to abortion.
