Defense Secretary James Mattis will make his first visit to Capitol Hill since his confirmation in the coming week.
Mattis is scheduled to testify Wednesday before the Senate Appropriations defense subcommittee alongside Chairman of the Joint Chiefs of Staff Gen. Joseph Dunford.
While the defense budget is the ostensible focus of the hearing, senators are sure to pepper the pair with questions on a wide range of defense issues.
The Trump administration released its first budget outline Thursday, showing a proposal to give the Pentagon $639 billion. That would be broken down into $574 billion for the base budget and $65 billion for a war fund.
The budget released Thursday painted in broad brushstrokes, so senators will look for Mattis and Dunford to fill in the details of how the money would be spent.
Also look for senators to push Mattis to voice support for State Department funding. Trump's budget would cut State Department funding by 28 percent, and many lawmakers who oppose the cuts have invoked Mattis's 2013 statement that "if you don't fund the State Department fully, then I need to buy more ammunition."
Outside of money, look for questions on the strategy to counter the Islamic State in Iraq and Syria (ISIS). The Pentagon recently sent 400 Marines and Army Rangers to Syria, and is reportedly considering up to 1,000 more troops for the country.
Senators may also press Mattis and Dunford on North Korea, especially after Secretary of State Rex Tillerson said Friday that military options are "on the table" for dealing with the country.
The hearing is scheduled for 10:30 a.m. in the Dirksen Senate Office Building, room 192. http://bit.ly/2mX1xcK
