President Trump is heading to Capitol Hill tonight for his first presidential address to Congress, where he’s expected to lay out part of his budget plan. On Monday, Trump proposed increasing the military budget to just over $600 billion—a $54 billion increase—while deeply slashing the budgets of other agencies, likely including the Environmental Protection Agency and the State Department. Separately, President Trump is also expected to sign an executive order today aimed at reversing President Obama’s clean water regulation, known as the “Waters of the United States” rule. The regulation covers 60 percent of U.S. bodies of water and seeks to protect the waters from pollution. The executive order is expected to direct the Environmental Protection Agency and other federal agencies to review this regulation and to revise or rescind parts of it that do not promote economic growth.
