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

Tens of thousands of demonstrators took to the streets across Southern California on Saturday to voice their concerns over ongoing immigration raids and oppose the policies of President Trump, who they depicted as an aspiring monarch.

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

Thousands gathered at Houston City Hall for a lively protest early Saturday, cheering as local speakers decried President Trump’s immigration crackdown. Police officers in protective gear ringed parts of a subdued but attentive crowd.
