A federal judge on Monday temporarily blocked the National Park Service from revoking a permit for a continuous anti-Trump protest in Washington, D.C., after the display of a flag reading "86 47" that federal authorities consider potentially threatening to the president.

The Secret Service has interpreted the "86 47" message as a potential call for violence against President Trump, who is the 47th president. Court documents indicate that federal officers ordered the flag to be removed last week as part of the ongoing security concerns.

The protest has been operating under a 24-hour permit in the nation's capital, allowing demonstrators to maintain a continuous presence. The permit dispute arose specifically over the display of the controversial flag, which prompted the National Park Service to move toward revoking the demonstration authorization.

Meanwhile, the Trump administration's Department of the Interior has been implementing changes to D.C.'s Freedom Plaza, installing what officials describe as a patriotic display featuring Caesar Rodney and Revolutionary War soldiers. The plaza had previously been a site of significant activity during the George Floyd protests.

The temporary restraining order allows the protest to continue while the court considers the broader legal questions surrounding the permit revocation and First Amendment protections for political demonstrations in the capital.
