“It’s going to be a really powerful action,” Julio López Varona, co-director of Community Dignity Campaigns at the Center For Popular Democracy Action, told Newsweek in an interview ahead of the rallies.

That is why at least 300 protesters will be making their way to Bezos’ home, to deliver their message loud and clear Thursday afternoon.

The day-long protest will start on Capitol Hill, with protesters greeting Congress members returning from August recess.

Families affected by the Trump administration’s hardline immigration policies are also expected to share their stories at the Hart Senate Office Building, from around 9 a.m. to 3:30 pm ET, according to an itinerary for the march sent to Newsweek in advance.

Then, protesters will gather outside ICE’s offices in Washington, D.C., with community groups expected to lay hundreds of flowers outside the facilities before holding a moment of silence “to pay respects to those who suffered or died at the hands of the agency.”

The symbolic display will be a “somber” reminder “of the damage induced by his company,” organizers said in their itinerary. “Activists hope to demonstrate the widespread dissent of the role Congress and corporations have played in perpetuating the criminalization of immigrants in this country.”
