John Boehner, who leads Republicans in the U.S. House of Representatives, said on Monday that the selection of a replacement for Chuck Hagel as Secretary of Defense must be accompanied by a new look at U.S. military policies.
"This personnel change must be part of a larger re-thinking of our strategy to confront the threats we face abroad, especially the threat posed by the rise of ISIL," Boehner, the House speaker, said in a statement, signaling a potential tough tone by Republicans in Congress on the appointment.
