A popular meme making the rounds of conservative Twitter was instantly debunked on Saturday after pro-Trump tweeters forgot to crop out a sign in the background.

Trump supporters went all in on this tweet claiming to be a photo from Saturday's "Free Speech" rally in Boston, at which pro-Trump marchers were outnumbered by thousands of counter-demonstrators.

"Are these some of the white supremacists you're rioting over?" the tweet asked, showing a group of black people holding pro-Trump signs.

However, if you look closely, the sign behind the people in the photo says, "Welty Cleveland's Construction Manager" from the Welty Building Company located on West 10th Street in Cleveland, Ohio, indicating that the photo was taken perhaps last summer during the Republican National Convention in Cleveland and not in Boston.

Fake news! Sorry, Trumpers.
