WASHINGTON: A US appeals court let Donald Trump retain control on Thursday of California`s National Guard while the state`s Democratic governor proceeds with a lawsuit challenging the Republican president`s use of the troops to quell protests in Los Angeles.

Trump`s decision to send troops into Los Angeles prompted a national debate about the use of the military on US soil and inflamed political tension in the country`s second-most populous city.

On Thursday, a San Franciscobased court of appeals extended itspause on judge Charles Breyer`s June 12 ruling that Trump had unlawfully called the National Guard into federal service.

Trump probably acted within his authority, the court said, adding that his administration probably complied with the requirement to coordinate with Governor Gavin Newsom, and even if it did not, he had no authority to veto Trump`s directive.

`And although we hold that the president likely has authority to federalise the National Guard, nothing in our decision addresses the nature of the activities inwhich the federalised National Guard may engage,` it wrote in its opinion.

Newsom could still challenge the use of the National Guard and Marines under other laws, including the bar on using troops in domestic law enforcement, it added.

In a post on X after the decision, Newsom vowed to pursue his challenge.

`The president is not a king and is not above the law,` he said. `We will press forward with our challenge to President Trump`s authoritarian use of US military soldiers against our citizens.President Trump hailed the decision in a post on Truth Social.

`This is a great decision for our country and we will continue to protect and defend law-abiding Americans,` he said.

`This is much bigger than (California governor) Gavin, because all over the United States, if our cities, and our people, need protection, we are the ones to give it to them should state and local police be unable, for whatever reason, to get the job done.

Charles Breyer`s ruling was issued in a lawsuit against Trump`s action brought by Newsom.Breyer ruled that Trump had violated a US law governing a president`s ability to take control of a state`s National Guard by failing to coordinate with the governor.

It also found that the conditions set out under the statute to allow this move, such as a rebellion against federal authority, did not exist.

The judge ordered Trump to return control of California`s National Guard to Newsom. Hours after the judge acted, the appeal court put the judge`s move on hold temporarily.

Amid protests and turmoil in LosAngeles over Trump`s immigration raids, the president took control of California`s National Guard on June 7 and deployed 4,000 troops against Newsom`s wishes.

Trump also ordered 700 Marines to the city after sending in the National Guard.

At a court hearing on Tuesday on whether to extend the pause on Breyer`s decision, members of the judges panel questioned lawyers for California and the Trump administration on what role, if any, courts should have in reviewing Trump`s authority to deploy the troops.-Reuters
