Janet Napolitano

Homeland Security Secretary Janet Napolitano is stepping down from her position.

FOX News Radio's Mike Majchrowitz reports from the White House:

After more than four years, Janet Napolitano is stepping down to become President of the University of California.   In a statement, President Obama says "the American people are safer and more secure thanks to Janet's leadership."  She has presided over a build up of border security and handled threats ranging from the underwear bomber to the Fort Hood shootings.  Her departure comes at a sensitive time -- as the President tries to get immigration reforms through Congress.  Border security is a major concern there and this change in leadership could add uncertainty.

At the White House, Mike Majchrowitz, FOX News Radio.

READ a statement by President Obama on Department of Homeland Security Secretary Janet Napolitano's Announcement:

"I want to thank Secretary Napolitano for her outstanding work on behalf of the American people over the last four years.  At the Department of Homeland Security, Janet's portfolio has included some of the toughest challenges facing our country.  She's worked around the clock to respond to natural disasters, from the Joplin tornado to Hurricane Sandy, helping Americans recover and rebuild. Since day one, Janet has led my administration's effort to secure our borders, deploying a historic number of resources, while also taking steps to make our immigration system fairer and more consistent with our values.  And the American people are safer and more secure thanks to Janet's leadership in protecting our homeland against terrorist attacks. I've come to rely on Janet's judgment and advice, but I've also come to value her friendship.  And as she begins a new chapter in a remarkable career of public service, I wish her the best of luck."
