The 45th President has started as he means to go on by slashing several key policies from the country's books and signalling which countries he is keen to maintain friendly relations with.
Mr Trump and the new First Lady, accompanied by their family and vice-president Mike Pence and Karen Pence, have undertaken their first official engagement at the Washington National Cathedral where 26 faith leaders led a national prayer service.
After the service, the President plans to visit the CIA's headquarters in Langley, Virginia.The visit may well be a tense one after he criticised the CIA for concluding Russia was involved in hacking email to interfere in the presidential election.
President Trump appears to have dropped the controversial Transatlantic Trade and Investment Partnership (TTIP) between the US and the European Union (EU) while Theresa May is expected to meet Mr Trump as soon as possible following his remarks signalling a close relationship between the UK and the US.
The British Prime Minister could fly over to the US as early as next week after President Trump's team said the billionaire businessman wants to mimic the relationship between Ronald Reagan and Margaret Thatcher, who developed a close relationship in the 1980s.
The visit has been part of a secret plan being worked on by Downing Street over the last week.
A Whitehall source, said: "They are really, really keen to capture the Reagan-Thatcher idea: A new populist in the White House and a strong woman in Number 10.
"They want to rekindle that as soon as possible."
The Trumps have embarked on their first official engagement
A Downing Street spokesman told Express.co.uk plans had not been finalised yet but refused to deny Mrs May would travel to the United States as early as next week.
Hours after Mr Trump's inauguration on Friday afternoon, the future of the controversial Transatlantic Trade and Investment Partnership (TTIP) between the US and EU was thrown into doubt after the White House's website page on the deal was wiped.
Negotiations on the trade deal started in February 2014 but talks came to a standstill under Barack Obama.
During the election campaign Donald Trump said he would bin the beleaguered deal and it appears just hours into his presidency he has kept his promise.

January 20th, 2017. Donald Trump is sworn in as 45th President of America.
Details of leaders Mr Trump will meet should become more clear over the next few weeks.
However, he wasted no time in signalling which direction his presidency will go in by vowing to build a nuclear missile defence system to counter attacks from North Korea and Iran within minutes of his inauguration.
Mr Trump also announced plans to scrap Barack Obama's climate change prevention plans.
The TV personality said his predecessor's hard-fought plans, including cutting carbon emissions from coal-fired power stations, was "harmful and unnecessary" and he was committed to "maximising the use of American resources".
Mr Trump claimed he would increase wages by more than $30billion over the next seven years – despite a presidential term being four years – by diverting revenue from energy production to pay for rebuilding roads, bridges, schools and other strained infrastructure.

A Russia-US summit will most likely to be held in Reykjavik, which would replicate the famous cold war meeting between ronald Reagan and Mikhail Gorbachev in 1986.
Days before the inauguration, Mr Trump said he would consider dropping sanctions against Russia if Moscow helped tackle terrorism and worked the US on other goals.
A source who discussed a meeting plan with Mr Trump and officials at the Russian embassy in London, said: "The idea of a summit with Putin is definitely on the cards. The Russians are also keen on it."

She said Trump's views, what he says and politics are aimed at people she cares about – including "women, people of colour, immigrants and the LGBT community".
The actress added: ”If that is all true then it is important that we all stand up and be here, together, in solidarity."
Just before 3.30pm GMT (10.30am DST), Mr and Mrs Trump were joined by vice-president Mike Pence and his wife Karen at the Washington National Cathedral for a prayer service as their first official engagement of the presidency.
And later today the President will visit the CIA's headquarters in Langley, Virginia, a trip which could potentially be awkward as Mr Trump has heavily criticised the agency for concluding Russia had hacked emails to interfere in the presidential election.
