WASHINGTON (CBSMiami) – A top aide in Washington was formally nominated on Thursday to become a member of the president’s cabinet.

“I call upon Congress to put politics aside and confirm this incredible person,” said Trump.

President Donald Trump has tapped Kirstjen Nielsen, John Kelly’s principal Deputy Chief of Staff, as the Secretary of the Department of Homeland Security.

“Should I be confirmed, I will with the utmost strength and dedication protect our homeland,” said Nielsen.”I look forward to speaking with the members of the Senate – both Republicans and Democrats.”

She went on,  “Truly, there is nothing more valuable than to feel safe and secure in your homeland.”

In a statement released late Wednesday, the administration praised Nielsen for her “extensive professional experience” in the field.

Nielsen has worked within DHS under two presidents, including as the department’s Chief of Staff under President Trump.

“For the first time in history, a former employee at [DHS] is going to lead the department,” said Trump during her formal nomination.

If confirmed, Nielsen will replace Kelly who now serves s the president’s Chief of Staff.
