In Miami, the "No Kings" protest is unfolding near the Torch of Friendship, a symbol of the city's connection to the Caribbean and Latin America, with many protesters waving American flags.

As is the tradition with protests on Biscayne Boulevard in downtown Miami, cars passing by were honking steadily to show support, and people were banging pots and pans.

Ras Baraka, mayor of Newark, traveled between protests in New Jersey, heading from one in Montclair to another in Piscataway. He recounted what happened after his arrest last month following a clash at Delaney Hall, a private detention center.

"What I found out is that people who don't defend immigrants won't defend me either," he said. "We have to defend that right and defend it vociferously."
