Joe Biden is the new president of the United States as of noon on Wednesday, and the Democrat is determined not to waste any of his early leverage.

From stimulus checks and a mask mandate to reversing the Trump administration's policies and expanding healthcare access, the 78-year-old and his team are expected to take immediate action both through the narrow majorities the Democrats hold in Congress and executive orders.

1. Executive orders

The Biden team has trailed that it will issue a blitz of executive orders within the first 10 days. The Democrats have a narrow advantage in Congress after the surprise double victory in Georgia's Senate races, but the margins are tight and the party isn't in a position to pass sweeping legislation.

A memo from incoming chief of staff Ron Klain stated that Biden will issue executive orders on rejoining the World Health Organization and the Paris climate accord, as well as on tackling COVID-19, boosting the economy, helping those in financial difficulties as a result of the pandemic and ending the travel ban from Muslim-majority countries.

2. Ghost of Trump

The Biden team will immediately reverse several Trump policies, but the 45th president isn't likely to fade into the background quietly – even without the use of his favorite social media accounts.

Trump's Senate impeachment trial is likely to go ahead in the first 100 days, despite calls for it to be held back. The trial could distract from the Biden agenda and delay the appointment of his cabinet, while repeats of the violence seen on January 6 could overshadow his policy plans.
