Donilon to be named National Security Adviser

UPDATED 10:25 AM: A White House adviser tells NBC News that Deputy National Security Adviser Tom Donilon will succeed James Jones as National Security Adviser. Jones is stepping down today.

Donilon, who had said he was not interested in the position of chief of staff to the president, was widely believed to have his sights set on the post as National Security Adviser.

NBC's Andrea Mitchell also reported Jones is known to have recommended that Vice Chair of the Joint Chiefs Gen. James Cartwright replace him.
