About 100 people from around the country gathered under the blazing sun outside the D.C. jail on Saturday to protest the arrest of those involved in the Jan. 6 Capitol riot.

“Let them go! Let them go! Let them go!” the crowd chanted.

While MAGA hats and Trump apparel were mostly missing outside D.C. Central Detention Facility by request of the event organizers, many sported bright-red hats and carried signs with slogans such as “protests are not insurrections” and “patriots are not terrorists.”

The rally was organized by Look Ahead America, a nonprofit organization that aims to give voice to “rural and blue-collar patriotic Americans who are disaffected and disenfranchised from the nation’s corridors of power.”

Since the deadly Capitol riot, more than 500 people have been charged by federal prosecutors for participating, including arrests of alleged and confirmed members of several far-right groups such as the Oath Keepers and the Proud Boys.

The group Saturday was protesting about 50 people who are being held in the D.C. jail, who they called “nonviolent American patriots.”

Matt Braynard, founder and executive director of Look Ahead America, invited people to read letters from inmates. In between songs and prayers, the crowd chanted and cheered, hoping those inside the jail could hear.

“We will never let this happen again,” Braynard said through a megaphone.

Barbara Turpin, 63, woke up at 3:30 in the morning to drive to D.C. from Rochester, N.Y., for the rally because her son, Dominic Pezzola, 44, was being held at the jail.

Prosecutors say Pezzola, who was a member of the Proud Boys, was among the first people to break through barricades onto the Capitol grounds and led the smashing of a window on the Senate side of the building with a riot shield taken from police.

“Can you see me, honey?” Turpin said to her son on the phone while waving in the direction of where she believed his cell was located. A hand waved back through the sliver of window as Turpin wiped away tears.
