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

Thousands gathered in Daley Plaza and in suburban events in protests timed to coincide with a military parade in Washington celebrating the Army's 250th anniversary and President Donald Trump's 79th birthday.

Following a week of protests across the country, nearly a dozen rallies are planned for the area this weekend, including one in downtown Raleigh.

Millions marched in cities and towns across the U.S. in "No Kings" protests to rally against the Trump administration.
