Paul Rosenzweig, a former U.S. Department of Homeland Security Deputy Assistant Secretary for Policy, joins Tom Fitzgerald on this episode of the On The Hill podcast. Rosenzweig is now a Senior Fellow at the R Street Institute, a foreign policy think tank in Washington. We look at the removal of John Bolton as National Security Advisor, what would happen if the Secretary of State takes over the job and the subsequent national security implications. In addition, why has foreign policy been largely absent as a topic in the Democratic presidential campaign?
