American Democratic presidential contender Hillary Clinton told ABC News Tuesday in a last-minute bid to garner votes in the Pennsylvania primary that she would put Iran in the cross-hairs to knock out its nuclear development program if elected president.

"I want the Iranians to know that if I'm the president, we will attack Iran," she said, hoping the tough talk would help in her face-off against opponent Barack Obama.  The two Democratic US Senators are still in a dead heat for the Democratic Party's nomination for president.
