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

HOUSTON, Texas (KTRK) -- It was a day of demonstration in downtown Houston on Saturday for the "No Kings Day" protest. People are taking a stand against what they say is an overreach of President Donald Trump's administration when it comes to immigration enforcement.

With No Kings protests planned Saturday in the Houston area, local organizers are calling for peaceful rallies, while officials like Mayor John Whitmire say they are working with organizers "to ensure that First Amendment rights are respected while maintaining public safety.

The largely peaceful protests during the "No Kings Day" demonstration in downtown Los Angeles took an intense turn in the afternoon. Police ordered the crowd to disperse at about 4:15 p.m. PDT near Alameda Street and Temple Avenue, according to the Los Angeles Police Department's Central Division.

Organizers intend for the protests to counter the Army’s 250th anniversary celebration — which Trump has ratcheted up to include a military parade.

The "No Kings" protests are part of a nationwide movement coinciding with President Trump's birthday and a military parade in Washington, D.C., aimed at challenging the militarization of public celebrations. Houston's demonstration is set to begin at 10 a.m. Saturday at City Hall.

A suspect was arrested in connection with threats made against state lawmakers who planned to attend Saturday's "No Kings" protest at the Texas Capitol in Austin, according to the Texas Department of Public Safety.
