Trump Supporters Protest at Mar-a-Lago After FBI Raided Ex-President's Home

The FBI raid on Donald Trump's home immediately turned political ... with pro-Trump protesters gathering in front of Mar-a-Lago ... claiming it was a witch hunt.

As we reported, the FBI descended on Trump's home Monday ... on the hunt for classified and unclassified materials that Trump allegedly took from The White House when he left ... materials that should have ended up at the National Archives.

Trump improperly and allegedly illegally took a slew of materials that should have stayed in D.C., and months ago surrendered 15 boxes of stuff, but the feds believe he didn't turn over all of it.

A judge signed a warrant after determining there was probable cause the former President committed a crime by withholding the materials, which allowed the FBI to conduct the search. It's the first time in American history the feds raided the home of a former president.

This all didn't sit well with Trump supporters, who were weirdly celebratory as they encircled Mar-a-Lago. They played dance music ... not exactly the sign of angry protesters.

As for Trump ... he reportedly told his fans, "Another day in paradise."
