WATCH: Paul Ryan speaks in Lima

Paul Ryan speaks to supporters in Lima, Ohio on Sept. 24.

Republican vice presidential candidate Paul Ryan spoke to supporters at a town hall in Lima on Monday, Sept. 24.

Among many routine campaign issues, Ryan promised supporters a limited government and free enterprise if he and Mitt Romney were elected this November.

"Here is our plan for economic growth, for limited government, and economic freedom, and if you elect us, we will put it in place. This is the covenant we are asking for. Thatâ??s what elections are. We establish a covenant with the people who send us to represent them," he said.

Ryan also described President Barack Obama's handling of the recent riots in the Middle East as a threat to national security.

"If we keep showing that the only thing we're going to keep doing is gut our military, that projects weakness abroad. And by projecting weakness abroad, our adversaries are more tempted to test us and our allies are so much less willing to trust us," Ryan said. "We need peace through strength, we need a strong military. Because if we have a strong military, then America is strong, and we're more peaceful and we're more prosperous and that keeps us safe here at home."

Ryan will continue a three-day bus campaign tour through Ohio in Cincinnati on Tuesday.
