The demonstrations follow more than a week of large-scale protests in Los Angeles against Mr. Trump’s immigration crackdown and his decision to deploy the military there. Note: This map shows protests that have been confirmed and is not comprehensive.

The protests are aligned with President Donald Trump's June 14 military parade in Washington D.C., which is set to honor the U.S. Army's 250th anniversary, organizers said. June 14 is also Flag Day and Trump's 79th birthday.

That’s part of why George Atkinson, a former high school government teacher, felt compelled to join a protest in downtown Houston on Saturday. The 89-year-old affixed a sign to his walker that read, “The clothes have no emperor! He’s all hat and no cattle!”
