Reports state supporters started lining up early in the morning with one claiming to have been in line since Thursday night. Other reports state upwards of 20,000 people were in line for the 11,000 capacity venue.

The rally is for Republican Josh Hawley who is running against the Democrat incumbent Claire McCaskill in the November election.

Local Fox reporter John Brown, "Police tell me the JQH Arena May get to capacity. 11,000-plus expected at Trump/Hawley event in Springfield. First people in line at 5:30am. Line is 2 miles long. @FOX2now @fox4kc"

CNN's Kaitlin Collins, "Heading into the arena for President Trump's rally in Springfield, Missouri tonight. A man waiting in line right outside the doors told me he's been here since 9 p.m. last night, despite the on and off drizzle."
