Exclusive: Meet the New Secretary of Homeland Security, Markwayne Mullin

Amid the longest funding lapse in the history of the U.S. Government, the Department of Homeland Security has seen a change in leadership, but before former Oklahoma Senator Markwayne Mullin can fully take charge of the department, he first needs to convince Democrats to restore its funding.

Newly appointed Secretary of Homeland Security Markwayne Mullin sat down with Bret on Monday to discuss his approach to leading the embattled department, clearing the air on his stance towards sanctuary cities and ICE reforms, how his approach will differ from his predecessor, and sharing what he feels are the biggest pros and cons of his new position.

This interview first aired Monday, 04/06 on Special Report.
