Democratic Senator Elissa Slotkin says the price tag for a prolonged conflict with Iran is likely “very, very high” and signals she won’t support supplemental funding for the Pentagon without a clearer breakdown of how existing defense dollars are being spent. Slotkin, who served three tours in Iraq alongside the US military as a CIA analyst, calls Iran's use of drones a "new era of warfare" for the United States, and urges clearer objectives from the White House. She speaks on the late edition of Bloomberg’s "Balance of Power." (Source: Bloomberg)
