Obama Vows Justice for Libya Killings While Campaigning

Promises at rally in Colorado to get killers

President Barack Obama resumed campaigning for re-election as his administration grappled with the aftermath of attacks on U.S. diplomatic outposts in Egypt and Libya.

"We are going to bring those who killed our fellow Americans to justice," Obama said at a rally today in Golden, Colorado.

Obama was wrapping up a two-day trip in Colorado after a stop in Nevada yesterday; both states are battlegrounds in November's election. Obama's agenda for the previously scheduled campaign swing was overtaken by the assaults on U.S. diplomatic outposts in Egypt and Libya and the deaths of the U.S. ambassador to Libya and three other Americans in Benghazi.
