GOP presidential candidate Walker talks tough on China while campaigning in Iowa

GOP presidential candidate Scott Walker is renewing his call for President Barack Obama to cancel an official state visit with the president of China in response to slumping U.S. stock markets.

The Republican governor from Wisconsin said Wednesday following a campaign stop in Denison, Iowa, that such a move would not hurt trade with states like Iowa or Wisconsin.

Walker first called for the state visit to be canceled Monday. He defended it on Wednesday when asked about possible negative repercussions for agricultural states like Iowa and Wisconsin that combined do more than $2 billion in trade with China.

He says instead of inviting the Chinese president to a state dinner, Obama should "be taking them to the woodshed."

Walker is on a seven-stop, two-day campaign swing in rural southwest Iowa.
