Iowa Republicans will hear from Sarah Palin at the party's annual Ronald Reagan Dinner in September.

"The Iowa GOP is pleased that Gov. Palin is traveling to Iowa to join the battle to return principled, conservative leadership to Iowa," Matt Strawn, the party chairman, said in a statement. "Our economic and personal freedoms are under attack in Washington, DC and Des Moines. I know Iowa Republicans will be energized and motivated by Gov. Palin to stand up and fight for these principles all the way to Election Day and beyond."

There are at least two competitive House races and the gubernatorial contest happening in Iowa this cycle. The dinner, dubbed "A Salute to Freedom," will take place Sept. 17.
