Congress and defense policy: A conversation with Rep. Mac Thornberry, R-Texas Monday, Mar 02, 2020 10:00 AM–11:00 AM EST Brookings Institution Falk Auditorium 1775 Massachusetts Avenue N.W. Washington, DC 20036 Foreign policy is the domain of the executive branch, but Congress plays a key constitutional role by passing budgets and conducting oversight. As the Department of Defense reorients its strategy and outlook to deterring, and if necessary, defeating near-peer great competitors, Congress must ensure that the department is building a force that will address the nation’s security challenges while also stewarding U.S. taxpayer resources. On March 2, Rep. Mac Thornberry, R-Texas, will join Senior Fellow Michael O’Hanlon in a conversation on defense policy. Now in his final term, Rep. Thornberry is the ranking member of the House Armed Services Committee and a distinguished former chairman. An advocate of on-time annual defense budgets, Rep. Thornberry was instrumental in realizing the Trump-era increases in defense spending, and in advancing the Obama-era “Third Offset” to enhance U.S. competitiveness before that. Their conversation will span the defense budget, the role of Congress in overseeing the Defense Department, and the wide range of security challenges confronting the United States. Questions from the audience will follow.
