MACON, MO. (AP) -- Protesters opposed to President Barack Obama's scheduled tour of a north-central Missouri ethanol plant aren't waiting until his Wednesday arrival to speak out.

The Missouri Republican Party and a tea party group called the Macon County Patriots planned a protest Tuesday evening down the road from Poet Biorefining in Macon, with other groups also taking part.

Poet Biorefining was the state's first ethanol plant.

Obama is making a two-day Midwestern swing beginning with two stops on Tuesday in Iowa.

The visit to Macon is set for Wednesday morning, followed by a stop in Quincy, Ill.
