First order of business: bolstering the New York Stock Exchange.
Trump tweeted Saturday morning that he would "very much appreciate" that the Saudis would list Saudi Aramco in the USA, saying it is "important to the United States!" Important to the United States!
Aramco, which controls Saudi Arabia's massive energy assets, plans to list almost five percent of its shares in the stock market.
The public offering of shares of Aramco, the world's largest oil producer, is part of Saudi government plans to sell state assets as a recession slows Riyadh's effort to eliminate a budget deficit caused by low oil prices.
A public listing of Aramco, which has been valued at around $2 trillion, would be the biggest IPO in history. His visit to Saudi Arabia in May heralded the signing of billions of dollars worth of contracts between USA and Saudi companies, including 16 agreements with Saudi Aramco.
London and other major cities with exchanges have also been vying for the global listing.
NY is vying with London, Tokyo and other locations to attract the much-anticipated listing, which could be the biggest in history.
While previous presidents have championed the NYSE's role in worldwide finance - Ronald Reagan and George W Bush visited the floor during their presidencies - typically a president would not weigh into the private company decision of where to list its shares.
Aramco's IPO will provide much of the financing for the Vision 2030 project led by the new crown prince of Saudi Arabia, Mohammad bin Salman, to modernize the nation's economy and reduce it dependence on petroleum.
