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.

Saturday tens of thousands are expected to turn out in Philadelphia, which is holding the so-called flagship No Kings demonstration against Donald Trump administration policies.

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.

Philadelphia District Attorney Larry Krasner says immigrants demonstrating in this weekend’s ‘No Kings’ protests do not have protections from ICE. He also blasted President Donald Trump for ICE raids across the country.
