National Security Gets New Leading Man

WASHINGTON (AP) - President Barack Obama is announcing the resignation of retired Gen. James Jones as his national security adviser, the second high-level staff change at the White House in as many weeks.

Obama says deputy national security adviser Tom Donilon will take over.

Speaking in the White House Rose Garden, Obama said he has relied every day on Jones' advice and counsel.

Last Friday, also in the Rose Garden, Obama announced the departure of his chief of staff, Rahm Emanuel.
