Huntsville police told Al.com that Sealy got into a fight with a person at the rally, and eventually pulled a weapon out.

He was arrested for possessing a firearm within 1,000 feet of the protest.

"He pulled out a gun. I saw him holding it out in front of him. We just started screaming for everybody to drop to the ground," Ava Caldwell, a rally organizer, told CBS affiliate WHNT. "We all dropped to the ground crying."

The reports note that no shots were fired and no one was injured.

Thousands gathered in cities across the country on Saturday to protest against the Trump administration's immigration policies. The demonstrations come in response to a "zero tolerance" policy that resulted in thousands of families being separated at the U.S.-Mexico border.

Trump signed an executive order to end that practice in June, but many continue to question how the administration will reunite the families already separated.
