Chris Pratt is already a guardian of the galaxy and now the actor has volunteered his Parks And Recreation alter ego to fill the empty spot left by dismissed FBI director James Comey.

After US President Donald Trump fired the bureau's top man earlier this week, Pratt tweeted footage of "FBI Agent Burt Macklin" in action, adding: "Just lemme know."

The character was the joke persona of Andy Dwyer in the television series which propelled the Guardians Of The Galaxy actor to fame.

The joke came as shock swept the US over the sacking of the man leading the investigation into contact between Russia and President Trump's election campaign.

The Republican president said he fired Mr Comey "because he was not doing a good job".
