The 12-year-old daughter of two undocumented immigrants delivered an emotional speech at the Families Belong Together rally in Washington, D.C., on Saturday.

The girl, identified only as “Leah” in a CNN video, fought back tears while speaking out against the Trump administration’s “zero tolerance” policy, which has resulted in more than 2,000 migrant children being detained and separated from their parents.

“Why do they hurt us like this?” She said. “It is unfair that they get to spend time with their families today while there are children in detention centers and in cages all alone missing their parents, who are thrown in jail.”

Leah shared her personal fears that her mother will be arrested and deported, saying that Immigration and Customs Enforcement wants to “take away my mom from me.”

“I don’t like to live with this fear, it’s scary,” Leah said. “I can’t sleep, I can’t study, I am stressed.”

“I don’t understand why this administration won’t support mothers who just want a better life for their children,” she continued. “This needs to change.”

Leah said that she wanted to be “an example” to other kids with undocumented parents, and to tell them “not to give up.”

“We are all human and deserve to be loved and cared for,” she said. “We are children. Our government has to do the right thing and stop separating us from our parents.”

Leah spoke at the Families Belong Together rally in D.C., one of hundreds of marches organized throughout the U.S. and abroad Saturday in protest of the Trump administration’s immigration policies.

Trump signed an executive order earlier this month to halt family separations at the border, but the administration has come under fire for not presenting a plan to reunite the families that have already been separated.
