WASHINGTON - Responding to terror attacks like the Fort Hood shooting rampage and the failed Times Square bombing, President Barack Obama is adding homegrown terrorists to the administration's top national security priorities.

Obama's top counterterrorism adviser, John Brennan, said Wednesday the administration's newly revised national security strategy document will place homegrown threats among the nation's top national security concerns.

Presidents use the national security strategy document to set broad goals and priorities for keeping Americans safe. The document has far-reaching effects on spending, warcraft and security strategies.

Obama's revision would be the first time that homegrown terror threats was a pillar of the document. President Bill Clinton did not mention domestic terrorism in his 1998 revision after the Oklahoma City bombing, and President George W. Bush made only passing reference to homegrown terrorism in 2006 document.

Brennan said the revision will address homegrown extremists like the Pakistani-American charged in the failed Times Square bombing. Brennan discussed U.S. citizens like Najibullah Zazi and David Headley, who were charged with plotting terrorist attacks.

The White House is expected to release the document this week.
