Donald Trump arrived at the US Capitol where he will be sworn in as the 47th president on Monday.
"Good morning," Trump said as he entered the Capitol accompanied by President Joe Biden. Asked how they felt, Biden responded, "Well."
Trump is to declare a national emergency at the US border with Mexico when he assumes office, an incoming administration official told reporters, with the military set to have a key role.
"We are going to declare a national emergency at the border," said the official. "The Executive Order directs the military to prioritize our borders and territorial integrity."
Meanwhile, Trump will issue a series of executive orders targeting diversity programs and gender identity policies on Monday, moving swiftly to deliver on divisive campaign promises to dismantle "woke" culture.
An incoming White House official told reporters on Monday ahead of the presidential inauguration Trump will order the US government to recognize only two biological sexes as well as to end federal diversity programs. The policies will almost certainly face legal challenges.
"What we're doing today is defining that it is the policy of the United States to recognize two sexes: male and female," the official said.
"The Department of Treasury -- this is a little while ago now -- included diversity training that said all white people, regardless of how woke they are, contribute to racism. So, this type of funding, we're going to end at these (diversity) programs. We're going to end that."
Trump planned to "ask Congress to pass a bill establishing that the only genders recognized by the US government are male and female, and they are assigned at birth," his political program stated.
On the campaign trail Trump railed against diversity, equity and inclusion policies in the federal government and in the corporate world, saying they discriminated against white people -- men in particular.
