Protests were held around New Jersey and across the country on Saturday, as demonstrators demanded that the Trump administration immediately reunite migrant families that were separated at the U.S. border.

Thousands of protesters took to the streets of Newark, marching to the U.S. Customs and Immigration offices on Broad Street and then taking a knee in silent protest.

At City Hall in Newark, New Jersey's two Democratic U.S. senators denounced the Trump administration.

"We are here to remove the national stain that this president has created on our nation by tearing young children apart from their mothers and their fathers," said Sen. Bob Menendez. "That is not the America we know and it is not the America that we will stand up for."

"We the people must understand that the power of the people is greater than the people in power," Sen. Cory Booker told the crowd. "And so in this moral moment in America, it is not time to be a bystander or a spectator. Everyone must get on the field of justice and work and struggle and sacrifice."

Another large demonstration was held in New Brunswick.

The events coincided with a nationwide "Families Belong Together" rally movement that demands an end to the Trump administration's zero-tolerance immigration policies. More than 700 marches and rallies were held across the country Saturday, including in New York, Washington and other cities.
