Donald Trump now is slated to take the stage later in the afternoon at the DeltaPlex.
Trump had been slated to take the stage around noon but is delayed in Chicago, according to a campaign spokesman. Thousands of people are standing in front of Trump's podium and taking their seat inside the facility Monday, Oct. 31, ready to see the Republican presidential candidate speak.
Michigan Republican chairwoman Ronna Romney McDaniel and former U.S. Rep. Peter Hoekstra, R-Holland, were among the first speakers at the Halloween rally.
