Monday, Jan. 20, is Rev. Martin Luther King, Jr. Day, a federal holiday in America. Black Twitter users sent the hashtag #MLKDay trending on the social media platform.

The hashtag generated tens of thousands of tweets paying tribute to the slain civil rights leader. But one tweet in particular caught Black Twitter's eye.

The tweet was sent by the Federal Bureau of Investigation (FBI), who many accused of tapping Dr. King's phones in motel rooms and sending tapes of his sexual exploits to his wife, Coretta Scott King, pictured below with King and their first child, Yolanda King, in 1956.

The tweet accompanied a nighttime photo of a memorial to Dr. King installed at the entrance to the FBI Academy in Quantico, Virginia.

"Today, the FBI honors the life and work of the Reverend Dr. Martin Luther King, Jr. A quote from Dr. King is etched in stone at the FBI Academy's reflection garden in Quantico as a reminder to all students and FBI employees: "The time is always right to do what is right." #MLKDay

As they do every year when the FBI remembers King on his holiday, Black Twitter was ready to throw jabs and daggers.

Not willing to let bygones be bygones Black Twitter reminded the FBI that ex-director J. Edgar Hoover tapped Dr. King's phones and hounded him to his grave.
