At a rally in Waco, with more than two dozen military veterans and flag officers standing behind her, Clinton criticized Obama for being "missing in action" during key security decisions in the Senate and claimed that he had "no responsibility" when he gave an anti-war speech in 2002 as an Illinois state senator.
Her comments coincided with a new campaign ad released in Texas that asks voters who they want to answer the phone in the White House at 3 a.m. when "there's something happening in the world."
Obama criticized the ad earlier Friday, saying it was an attempt to "scare up votes."
Clinton disputed that notion in her speech Friday, saying, "Well I don't think people in Texas scare all that easily."
In a salvo against Obama that lasted several minutes, Clinton said, "There's a big difference between giving a speech at anti war rally as a state senator and dealing with an international crisis as president."
"There's a difference between giving a speech when you have no responsibility," she argued, "and having to step up and take charge and take the responsibility for your actions."
She charged that Obama was "missing in action" when he missed a Senate vote last year on a nonbinding resolution in that labeled the Iranian Revolutionary Guard a terrorist organization (Clinton voted for the measure and faced heat from Obama and other Democratic rivals for supporting a measure pushed by the Bush administration.)
She also said Obama was "missing in action" by failing in his chairmanship of a Senate subcommittee on Europe to hold a hearing on NATO's presence in Afghanistan, a fact she has emphasized in recent days on the campaign trail.
Gen. Wesley Clark, a Clinton supporter and the former Supreme Allied Commander of NATO, plugged the TV ad while introducing Clinton on stage and suggested that her tenure as First Lady prepared her to be president.
"She's been in the White House when the tough decisions were made," Clark said, looking over to Clinton. "I guess you've been at the bedside when that phone rang at 3 a.m. in the morning."
Clinton was joined at the event by three generals, including Clark, and a Navy Rear Admiral.
