Taking oath as the 47th President of the United States, Donald Trump said the "golden age" of America has begun and the country will be the envy of every nation.
In a message filled with hope and threats, interspersed with digs at the outgoing government led by Joe Biden, the Republican, who won a historic mandate in November despite losing in 2020, referred to the assassination attempt on him in Pennsylvania in July and said he was "saved by God to make America great again".
He also received standing ovations when he declared that he would announce a "national emergency" at the southern border in Mexico and a "national energy emergency" that would allow oil extractors to "drill, baby drill" - issues that had been key campaign pitches and resonated with his 'Make America Great Again' (MAGA) supporters.
Rattling off other key talking points of his campaign, which may have far-reaching consequences, the President said his administration would deport "millions and millions" of undocumented migrants, "tariff and tax" foreign countries, "take back" the Panama Canal and rename the Gulf of Mexico.
Trump also positioned himself as a "peacemaker and unifier", pointing to some Israeli hostages being handed back by Hamas, and said he would lead the United States of America to new heights - including by sending astronauts to Mars - and make the country "greater than ever".
