One of the biggest protests is expected to take place in Washington D.C'.s Lafayette Square, directly across the street from the White House, with turnout expected to top 50,000 people.
Almost 600 activists, protesting Donald Trump's "zero-tolerance" policy against illegal immigrants, have been arrested after staging an occupy sit-in at the Hart Senate Office building in the nation's capital.
The protesters occupied the Hart Senate Office Building on Thursday while wearing foil blankets that resembled those worn by children being held in detention facilities on the US-Mexico border.
They ended up at a Senate office building, where they sat on the floor with emergency blankets, like the ones some immigrants have been given at detention centers after crossing the USA border.
A main event in Washington, D.C.is expected to draw tens of thousands of marchers, two days after thousands of women marched to Capitol Hill and almost 600-including Rep. Pramila Jayapal (D-Wash.)-were arrested for demonstrating in the Hart Senate Office Building.
Capitol Police said the protesters were charged with the D.C. Code violation of crowding, obstructing or incommoding.
Protesters chant slogans outside a Federal court during a demonstration calling for the abolishment of Immigration and Customs Enforcement, or ICE, and demand changes in United States immigration policies, June 29, 2018, in NY.
Protesters marched from the courthouse in downtown Manhattan and made their way across the Brooklyn Bridge to join another rally in Brooklyn.
Democratic senators Mazie Hirono, Tammy Duckworth, Kirsten Gillibrand and Jeff Merkley, who have been critical of Trump's immigration policies, spoke with some of the protesters.
One protest sign read, "Compassion not cruelty" while another said simply: "Vote".
"The precipitating crisis, i.e. forced family separation, was a creation of defendants' own doing", the cities said in their request to be heard in the case. City and state officials say hundreds of separated children were brought here NY. "I just don't see how a human being would do such a thing".
Demonstrators will demand an end to family detentions and the return of at least 2,500 children separated from their parents at the country's southern border. Within 14 days, children under 5 were to be back with their parents, and within 30 days, children 5 and older were to be reunited with theirs.
"As a nation and a people we can do better", Lewis said. He also said his colleagues want to fix "this broken immigration policy".
She said organizers have notified police about their plans and expect the rally to remain peaceful. They've also posted downloadable posters and protest signs.
Galland said she and US Rep. Pramila Jayapal put out a call for protests less than two weeks ago, and they've been "overwhelmed" by the response.
"I'm a mom, and I think everyone I know that I've talked to about this issue has had a very visceral reaction", Sharaf said.
