It is my great honor to represent the men and women of DHS who work every day to enforce our laws and secure our nation.

Every day, we rely on a number of partnerships to help us accomplish our mission to secure our borders. State and local officials, interagency federal partners, Congress, and of course, our international partners. I have been with and will and continue to work with these partners.

I do absolutely believe that the climate is changing. I'm not prepared to determine causation.

Border security is the most basic and necessary responsibility of a sovereign nation.
