Tens of thousands of Americans joined "No Kings" protests across the United States against the Trump administration.

Thousands protested in Central Texas on "No Kings Day," opposing perceived authoritarianism on a day marking Flag Day and Trump's birthday.

More than 60 rallies are planned across Texas in a nationwide protest targeting the Trump administration. An arrest was made near Austin related to a threat against state lawmakers who attended a protest at the Capitol.

The Houston demonstration is one of several planned in the region throughout the day and is expected to draw thousands of protesters.

City leaders are addressing concerns after Texas Governor Greg Abbott announced the deployment of the National Guard to San Antonio ahead of the "No Kings Day" protest scheduled for this weekend. San Antonio Mayor Ron Nirenberg said the city received no "advance warning" of the National Guard from Abbott.

Despite peaceful demonstrations reported in multiple cities, violence flared at some anti-Trump protests over the weekend.

Saturday's No Kings protest is expected to draw thousands of people, said Kristi Pham of organizer 50501 Houston, which is calling for the event to remain peaceful, as they have in the past. Organizers also are collecting nonperishable food donations for several local food banks.
