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

Protesters across Southern California and the country took to the streets for ‘No Kings’ demonstrations against President Trump and the $45-million celebration of the U.S. Army’s 250th birthday, which coincides with Trump’s 79th.

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

Across the country, relatively few disruptions were reported during protests and marches where the mood ranged from joyful to defiant.

The threat had roiled the capital city, leading the state's Department of Public Safety to evacuate the Capitol building and surrounding grounds “out of an abundance of caution" around 1 p.m. DPS reopened the grounds around 4:40 p.
