Romney presses Obama on Libya attack before debate

WASHINGTON (AP) - Republicans pressed the Obama administration over the deadly attack on US diplomats in Libya, hoping to weaken the president just days before a final debate with Mr Mitt Romney that will focus on foreign policy.

The race to the Nov 6 election remains close, and it is not clear whether the shrinking number of undecided voters would be swayed by an overseas issue while worrying about the economy at home, which remains weak.

President Barack Obama and Mr Romney both retreated from the campaign trail to prepare for Monday's debate in Boca Raton, Florida, the third and final between the two rivals. They left courting voters in the critical swing states to their running mates, wives and surrogates.

Mr Obama left on Friday for Camp David, the presidential hideaway in Maryland's Catoctin Mountains. He was to remain there with advisers until Monday morning.
