Four men who unfurled a Trump 2020 banner at the Orioles game in Baltimore on Thursday were escorted out of the stadium while fans chanted, "Take it down" -- and it was all captured on video.
It all went down in the 8th inning of the Orioles vs. Blue Jays game ... after most of the fans had left Camden Yards because the Blue Jays were beating the hell out of the home team.
The men displayed the "Keep America Great" banner from an upper deck railing behind home plate -- and it hung for about 10 minutes before stadium officials took action.
You can see cops order the men to pull their sign up, which they do -- while basking in the boos from other pissed off fans.
FYI, the Orioles have an anti-banner policy at the stadium ... prohibiting fans from displaying ANY signs during the game -- especially if the team feels the signs are in "bad taste."
The men were eventually escorted out of the stadium -- but they didn't seem to care at all. In fact, it looks like they LOVED the attention.
Of course, Baltimore and President Trump have been in the news all week long ... POTUS called the city a "rodent-infested mess" and opinions from both party lines have gushed in ever since.
Trump supporters like Johnny Damon have said the President ain't wrong, telling TMZ Sports that toward the end of his baseball career, he found the city to be "scarier."
Baltimore's mayor, Bernard Young, disagreed ... saying, "It’s completely unacceptable for the political leader of our country to denigrate a vibrant American City like Baltimore."
