In Chicago, the rally grew so big that the march was canceled
CHICAGO In Grant Park, tens of thousands gathered for a rally that grew so large that organizers had to halt the planned short march through the city's downtown.
Unseasonably warm weather appeared to help bolster attendance.
The Chicago Transit Authority added extra cars to the city's L train service to help transport the mass of people. Still, the trains were packed to the gills.
Organizers, who projected more than 50,000 demonstrators, said the crowd appeared to have swelled to 150,000. It was held on the same site that former President Barack Obama used for his 2008 Election Night victory party.
"Our march route is flooded. There is no safe way to march. We are just going to sing and dance and make our voices heard here," rally and march co-chairwoman Ann Scholhmer told the crowd at Jackson and Columbus drives just before 11 a.m., according to the Chicago Tribune.
