In the interest of ensuring the safety of our attendees, including families with children, this joyful and peaceful march to protect every human life has been rescheduled,” the group said.

Protests took place in more than 1,500 cities on the same day that the president's birthday military parade, costing tens of millions of dollars, took place.

The demonstrations come on the heels of protests flaring up around the country over federal immigration enforcement raids that began last week and Trump ordering National Guard troops and Marines to Los Angeles where protesters blocked a freeway and set cars on fire.

Protesters criticized the administration's actions, including its crackdown on immigration, and condemned the fatal shooting of a Democratic Minnesota lawmaker earlier Saturday.
