Organizers are calling for Americans to attend demonstrations across the country to protest President Trump on his 79th birthday.

Rallies are expected in 2,000 cities across the U.S. on Saturday for No Kings Day protests against President Trump’s policies.

Approximately 4,000 protesters took to the streets in Palm Beach County and the Treasure Coast during three major rallies held on No Kings Day.

Around 2,000 protests were planned on Saturday in opposition to President Donald Trump. Large crowds turned out in cities like Portland, Denver, Chicago, Houston and Los Angeles – and in smaller communities in traditionally conservative areas.

Despite peaceful demonstrations reported in multiple cities, violence flared at some anti-Trump protests over the weekend.

Police officers in major cities suffered injuries at the hands of violent agitators over the weekend, with several rioters throwing fireworks and other objects at the officers.

As the military presence ramped up in Los Angeles, communities are preparing for the largest protests against Trump since he took office.

It coincides with Trump’s birthday and a military parade in Washington, D.C., which protesters have critiqued as a lavish use of taxpayer dollars.  More: 'No Kings' protests planned across US on June 14: See map of locations in Texas Here's what we know about planned protests in Austin and across Texas: 4:17 p.
