'No Kings' protests: Tensions rise in LA as crowd hurls concrete, police allege

A massive military parade is set to bring thousands to Washington, D.C., to mark the Army's 250th birthday on June 14 -- the same day as President Donald Trump's 79th birthday.

The Army has estimated more than 6,000 soldiers will participate in the event -- an all-day ordeal that's expected to include a fitness competition, festival and parade complete with tanks and infantry vehicles, helicopter flyovers and parachute jumps.

Here's what to know about the event.

Inside the preparations underway to secure the U.S. Army's 250th birthday parade on Saturday, which also falls on Pres. Trump's 79th birthday.

President Donald Trump is taking credit for Los Angeles being "safe and sound" the last two nights, writing on Truth Social that the "great National Guard, with a little help from the Marines, put the L.A. Police in a position to effectively do their job."

"They all worked well together, but without the Military, Los Angeles would be a crime scene like we haven't seen in years," Trump wrote. "Governor Gaven NewScum had totally lost control of the situation. He should be saying THANK YOU for saving his a--, instead of trying to justify his mistakes and incompetence!!!"

Trump's comments come after two nights of curfews in a part of downtown LA that has been the site of clashes between police and protesters over the last six days. The overnight curfew was issued by LA Mayor Karen Bass.

Trump's post also credits "a little help from the Marines," however, the Marines deployed by Trump have not begun service in LA.

A poll from the Washington Post and the George Mason University Schar School of Policy and Government found that Americans are largely split over if they support or oppose the protests in LA. Americans are also split over support for President Donald Trump sending the National Guard and Marines to respond.

Californians, however, are more supportive of the protests and far more opposed to Trump sending the National Guard and Marines.

A hearing is set for Thursday over Gov. Gavin Newsom's request to stop troops from coming to Los Angeles amid anti-ICE protests.

A U.S. District Court judge in San Francisco will hear arguments from California and the federal government starting at 1:30 p.m.

The hearing comes after Newsom filed an emergency motion Wednesday requesting the court's intervention following President Trump's deployment of thousands of National Guard troops and 700 Marines to the area.

A hearing is set for Thursday over Governor Newsom's request to stop troops from coming to Los Angeles amid anti-ICE protests. President Trump has deployed 4,100 National Guard troops and 700 Marines to the area.

President Trump's deployment is raising a host of legal questions regarding what he can and can't do with regards to the military on U.S. soil.

California leaders claim Trump inflamed the protests by sending in the military when it was not necessary, and did so illegally.

"The order we are seeking would invalidate the unlawful deployment of the National Guard to Los Angeles, and ensure that they are under the command of their actual commander-in-chief... Governor Gavin Newsom," said California Attorney General Rob Bonta. "It would also restrict the Marines to appropriate activities while in Los Angeles."

Newsom argues the situation, which has been relatively confined to a few square blocks in downtown Los Angeles, doesn't justify the use of Section 12406 in Title 10, which Trump invoked to send the National Guardsmen.
