At 4 p.m. as protesters were gathering, a counterprotester came to the scene — prompting angry chants to erupt from the main protest.

Hundreds of demonstrators were on the move Thursday evening in the Loop, with protest organizer saying they intended to head north over the Chicago River to Trump Tower. However, it's unclear if Chicago police are going to let them.

Several social justice groups have organized the demonstrations downtown. They're the latest in a string of protests in support of immigrant communities in the city.
