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.

"We expect all participants to seek to de-escalate any potential confrontation with those who disagree with our values and to act lawfully at these events..."

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