DES MOINES, Iowa (AP) -
Republican Sen. Rand Paul says it is a "valid question" to ask presidential candidates whether they would have invaded Iraq in 2003.
Paul told about 1,300 Iowa Republicans gathered Saturday at the state party's annual Lincoln Dinner that it's a valid question because "history repeats itself" in the Middle East.
The Kentucky senator and presidential candidate didn't name former Florida Gov. Jeb Bush, who stumbled on the Iraq question in recent days. Bush's brother, former President George W. Bush, ordered the invasion.
Paul questions whether Iraq is more stable today and argues that former Secretary of State Hillary Rodham Clinton should take questions about whether it was "a good idea" to topple Libya's Moammar Gadhafi.
Paul is among 11 presidential hopefuls addressing Iowa Republicans.
