WASHINGTON (AP) -- Vice President Joe Biden's supporters often brush off his slips of the tongue as a byproduct of the type of speak-your-mind politics that so many Americans crave. But this time, Biden's verbal blunders are causing more than just a momentary nuisance for his aides.
Twice in two days, Biden had to apologize to key U.S. allies in the fight against Islamic State militants after accusing the countries of aiding al-Qaida-linked groups in Syria. Not only did his comments threaten to jeopardize President Barack Obama's fragile coalition, it also put the White House on the defensive.
As Biden seeks to fashion himself as a credible alternative to Hillary Rodham Clinton in the 2016 presidential race, his latest missteps have rekindled lingering questions about his ability to serve as commander in chief.
