President Obama's motorcade is on its way to Seasongood Pavilion at Cincinnati's Eden Park, where thousands of supporters have filled the hillside opposite the Cincinnati Art Museum, eagerly awaiting his arrival.
Excerpts of the president's speech make it clear that the president intends to tout his administration's action this morning to file a complaint with the World Trade Organization over what it considers unfair trade practices by China in the export of autos and auto parts.
Mitt Romney's campaign has already called the action "too little, too late."
The president is scheduled to speak at 12:25 p.m.
Capt. Joe Wolf of the Cincinnati Fire Department estimated the crowd at Seasongood Pavilion at 4,500.
