WATCH | In a shocking upset, Donald Trump took the White House, culminating months of campaigning and controversy. Now that he's president, here are five things Trump has to do.
1. Calm the markets
Dow futures fell as much as 800 points at one point earlier Tuesday -- similar to how markets reacted to the so-called "Brexit" vote in June, when Britain shocked the world by voting to leave the European Union.
Global markets are in a tailspin, USAToday.com reports.
Trump will have to find common ground with businesses executives and leaders, both at home and abroad, to calm the markets.
2. Pick a cabinet
Newt Gingrich, retired Lt. Gen. Mike Flynn and Rudy Giuliani are among those who have been rumored to get spots in a Trump cabinet.
It's too early to tell who exactly will be picked and for what role. Trump will have to make sure his cabinet members have proven track records of success -- something critics have accused he himself of lacking.
3. Work with Congress
The House and the Senate may be Republican red, but that doesn't mean he'll have an easy time passing the legislation he wants.
Sen. Mark Kirk (Rep.- Ill.) and Sen. Susan Collins (R-Maine), among others, have been vocal about their displeasure with Trump.
During Trump's campaign many fellow Republicans tried to put some distance between them and the front-runner, especially after his well-publicized controversial statements.
4. 'Drain the swamp'
In a final campaign stop on Sarasota, Florida, Trump vowed to "drain the swamp," referring to the corruption he says is pervasive in Washington, D.C.
He'll have that on his list of things to do on Inauguration Day come January 20, 2017.
5. Build a wall
Trump has promised to build a wall along the U.S.-Mexico border and has said Mexico will pay for the barrier.
That could harm relations with one of the nation's biggest trade partners, but during his concession speech he did he extended an olive branch -- saying for people in all nations, "we will seek common ground not hostility."
