Mr Trump has made a number of ambitious pledges for his first day in office, and has vowed to “cancel every unconstitutional executive action, memorandum and order issued by President Obama.”
His advisor Stephen Moore added: “We want to identify maybe 25 executive orders that Trump could sign literally the first day in office.”
While today is technically the first day of his term, Mr Trump plans to take the weekend off before getting to work.
Speaking to Michael Gove for The Times, he said: “Day one – I will consider to be Monday as opposed to Friday or Saturday. Right? I mean my day one is gonna be Monday because I don't want to be signing and get it mixed up with lots of celebration.”
But what will President Trump do on his first day in office?
One of Mr Trump’s first actions after his inauguration was to sign an executive order stating that his administration will “seek the prompt repeal” of the Affordable Care Act – commonly known as Obamacare.
While the order does not change any laws, it directs the secretary of health and other politicians to interpret the Affordable Care Act as loosely as possible to lessen financial burdens on individuals, insurers and health care providers.
Mr Trump will continue working to scrub out Obamacare on his first day of work. A statement on his website vows: “On day one of the Trump Administration, we will ask Congress to immediately deliver a full repeal.”
The new President has long opposed Obamacare and has called it an “incredible economic burden”. He has no plans to directly replace it.
