A Washington, D.C., bar is offering $5 “Moscow Mueller” drinks after former national security adviser Michael Flynn pleaded guilty to lying to the FBI on Friday.

The Bird, a restaurant located in Washington’s Shaw neighborhood, offers the special whenever special counsel Robert Mueller unveils a new indictment or guilty plea in his investigation of Russia's meddling in last year's presidential election.

The drink’s name is a play on the name of the Moscow Mule, a cocktail made with vodka, ginger beer and lime juice traditionally served in a copper mug.

Flynn pleaded guilty to lying to FBI agents about his contacts with former Russian Ambassador Sergey Kislyak. As part of his plea deal, Flynn has agreed to fully cooperate with Mueller’s probe.

He becomes the first person to hold a formal position in the Trump administration to be charged in the investigation.

The Bird introduced the $5 “Moscow Mueller” last month after former Trump campaign chairman Paul Manafort and his business associate, Richard Gates, were also indicted in the probe.

The Bird has previously offered discounted drinks whenever Trump fires someone from the White House. It originally made the offer after the departures of former chief strategist Stephen Bannon and former communications director Anthony Scaramucci.

The restaurant offered a special cocktail called “the Mooch” following Scaramucci’s firing and soon after began offering discounted drinks “anytime Trump fires a White House official,” according to its Twitter profile.

The Bird isn't the only D.C. bar to explore Trump-themed specials. During former FBI Director James Comey's Senate testimony on the Russia probe in June, Union Pub offered free drinks every time Trump tweeted about him.
