James Comey

James Comey's appearance before the Senate Intelligence Committee later will be among the most dramatic congressional testimonies in America's history.

Mr Comey, who was fired as FBI director last month, could cause real problems for President Trump.

For a few hours, the nation will be watching on. In Washington DC, bars are gearing up for a blockbuster moment.

Shaw's Tavern is serving up a shot of Russian vodka with people's morning "covfefe".

It's hosting "Comey hearing Covfefe", with FBI sandwiches available as people watch events unfold on their screens.

Sky News, as well as other TV networks will be broadcasting the coverage in full, which is set to begin at 10am. (3pm UK time)

Mr Comey has said it is the only public testimony he will give on recent events.
