Homeland Security Secretary Janet Napolitano says terrorists who are U.S. citizens or live in the country legally and plot against the U.S. are just as big of a concern as international terrorists.
She says that when she started as secretary a year ago, the focus was largely on international terrorists who want to harm U.S. interests. But in the past year, more of the violent extremism that has been seen overseas is showing up in the U.S.
She says officials need to drill down and analyze the factors that make a young person, raised in the U.S., migrate to extremist beliefs and actions.
Napolitano was speaking to governors who are in Washington for their annual conference.
