Trump campaigned on relatively vague promises to repeal Obamacare, create jobs, build infrastructure, defeat ISIS, and radically change the country's immigration policy. This address, which the White House press team is already calling his "biggest speech yet," is his opportunity to explain what Congress needs to do to accomplish those goals.
Congress will be eager to hear how the president wants to tackle a repeal of Obamacare and see if he embraces any of the details in the replacement plan draft that House Republicans are currently working on. According to Politico, that plan would shrink subsidies and eliminate Medicaid expansion.
Congress will also be interested in finding out more about how Trump intends to pay for his proposed budget plan, which would bump up military spending to $54 million and increase spending on law enforcement and infrastructure. It's likely that the money will come from other departments, although it's not yet clear which ones.
