A man was arrested after DPS identified a “credible threat” toward legislators attending Saturday’s “No Kings” protest at the Texas State Capitol.

A day of peaceful demonstrations in Austin took a turn for the worse following the registered part of Austin's "No Kings" protest held at the Texas State Capito

"With the exception of a small number of agitators, the event remained largely peaceful," the Austin Police Department said.

On the same day Melissa Hortman and her husband were murdered in a "politically-motivated" assassination, more "politically-motivated" violence occurred at peaceful protests across the country.

Saturday's event at the Capitol remained peaceful. The Texas Department of Public Safety made one arrest earlier in the day related to threats against state lawmakers who were expected to speak.

Millions of people across the country protested the Trump administration across on Saturday, including in Austin.

The LAPD said on social media that the people in the crowd were throwing "rocks, bricks, bottles and other objects" while they were near the federal building.

U.S. Rep. Lloyd Doggett, another elected representative speaking while under apparent threat of assassination, gave a roundup of recent disturbing news headlines. He pointed to the shooting in Minnesota, and the incident Thursday when California Sen. Alex Padilla was aggressively arrested on camera. The crowd booed.
