Thousands of anti-Trump protests are erupting across the United States this weekend under the banner of “No Kings” day.

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

At noon Saturday, protesters were crowded into City Hall Plaza in Downtown Dallas and Burk Burnett Park in Downtown Fort Worth.

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.

Dozens of No Kings protests are scheduled for June 14 in Texas, including in Austin, Houston and San Antonio. Arlington: 10 a.m. to noon at Arlington Sub Courthouse, 700 E. Abram St.

"No Kings Day" is a nationwide day of peaceful protest organized to coincide with a military parade in Washington, D.C., marking the 250th anniversary of the U.S. Army. According to CBS News, the parade and related festivities are expected to cost between $25 million and $45 million.

Opponents of President Donald Trump’s administration are set to rally in Dallas, Fort Worth, Frisco, Arlington and other North Texas cities.

The Texas Department of Public Safety says a concerned citizen contacted local authorities to report a man was "on his way to the protest," at the State Capitol in Austin Saturday and was "planning to harm state lawmakers” attending a protest there.
