"Starting tomorrow, I will act with historic speed and strength and fix every single crisis facing our country. We have to do it," Trump told his supporters at the Capitol One Arena, which was full to its capacity of 20,000 for a "Make America Great" victory celebration, with a large number of people waiting outside in chilling cold

Trump, 78, made a stunning comeback when he defeated Vice President Kamala Harris in last year's general election to become only the second person in US history to be sworn in as the president after a gap of four years

Trump, who will replace Joe Biden as the 47th president of the United States on Monday, arrived at the US Capitol on Saturday

On a jam-packed day full of engagements, Trump addressed thousands of his supporters at what he called a 'victory rally'

"Before even taking office, you are already seeing results that nobody expected to see. Everyone is calling it the Trump effect. It's you. You're the effect," Trump said

"Since the election, the stock market has surged, while small business optimism has soared a record 41 points to a 39-year high. Bitcoin has shattered one record after another. Major investment company DMACC Properties has announced that it will invest between USD 20 billion and USD 40 billion in the US

"SoftBank, another great company, has pledged between USD 100 billion and USD 200 billion. These are all investments that are only being made because of the fact that we won the election," he added

Referring to meeting Apple CEO Tim Cook on Sunday, Trump said, "He said they're going to make a massive investment in the US because of our big election victory"

Giving an insight into his Day 1 plans, he told the cheering crowd, "Our incoming administration has achieved all of this in the Middle East in less than three months without me being the president. We've already achieved more than what they've (Joe Biden administration) done in four years"
