PHILADELPHIA (AP) — Cities large and small were preparing for major demonstrations Saturday across the U.S. against President Donald Trump, as officials urge calm, National Guard troops mobilize and Trump attends a military parade in Washington to mark the Army’s 250th anniversary.

The anti-Trump group “No Kings“ planned the protests to coincide with Saturday’s military parade in Washington, D.C. The group, on its website, states that “No Kings is a nationwide day of defiance” to “reject authoritarianism — and show the world what democracy really looks like.”

Brevard County Sheriff Wayne Ivey warned that "peaceful protests are part of our democracy, but the key word in that is 'peaceful.'"

Protests against immigration enforcement policies under former President Donald Trump are set to take place across Central Florida this weekend, as part of a nationwide "No Kings" mobilization timed to coincide with a military parade in Washington,

As a military parade rolls through Washington, DC, on Saturday – President Donald Trump’s birthday – millions of Americans are expected to protest in what organizers predict will be the strongest display of opposition to Trump’s administration since he took office in January.

Protests are taking place in Florida and nationwide on June 14, the same day as the military parade in Washington DC.
