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.
