Washington (AP) - Two senior administration officials say Gen. James Jones is resigning as President Barack Obama's national security adviser.

Officials who spoke on condition of anonymity because the decision has not yet been made public said that Jones will be replaced by Tom Donilon, the deputy national security adviser.

President Barack Obama will announce the change on Friday afternoon in a Rose Garden ceremony with Jones and Donilon.

The officials said that Jones, whose resignation will be effective in two weeks, had planned from the start of his tenure to leave the position at about the two-year mark.
