'Too dangerous to do anymore': Sacha Baron Cohen on Borat
(CNN) —  

The hand-scrawled signs in all colors and sizes reflect the thousands of Americans participating in rallies Saturday against the Trump administration’s “zero tolerance” policy toward undocumented immigrants.

From New York to Atlanta, signs carried by marchers painted a kaleidoscope of outrage over the more than 2,500 undocumented children who were separated from their parents in the weeks since the controversial policy took effect.

In New York, a little girl with dark hair held a bright yellow sign that read, “Mr. President Why do you like Mexican food but not the Mexican people? Families belong together.”

The caption on an Instagram photo of the girl reads: “The radicalization of Willa Gray.”

Another girl named Andromeda, who will turn 2 in August, marched with her father in New York with a sign that demanded, “Release my friends.”

Also in New York, Alex Ogle and Megan Harrison protested the actions of US Immigration and Customs Enforcement.

“I prefer crushed ICE,” one of the signs read.

In Washington, Margaret Stokes, a teacher from Leesburg, Virginia, marched with a sign that read, “Where are the children?”

Another one had a sketch of a baby onesie with the words, “Where is my mother?” and the question: “Do you care?”
