Donald Trump has a button on his desk to summon a butler to bring him a Coke

Democrats were nervous about the prospect of Donald Trump having his finger hovering over the button.

But perhaps they were worrying about the wrong button.

The US president has a box on his desk in the Oval Office of the White House that contains a single button – and he is using it to call a butler to bring him a Coke.

The wooden box sits on the Resolute Desk and has been a fixture there for previous presidents.

It’s just unclear if previous presidents used it to order a glass of Coca-Cola.

Mr Trump’s button-pushing habit was revealed in an interview with the Associated Press ahead of his 100th day as president.

AP journalist Julie Pace wrote: ‘A man accustomed to wealth and its trappings, Trump has embraced life in the Executive Mansion, often regaling guests with trivia about the historic decor.

‘With the push of a red button placed on the Resolute Desk that presidents have used for decades, a White House butler soon arrived with a Coke for the president.’

Mr Trump has already been pictured during his presidency with a glass of Coca-Cola on his desk in the Oval Office, but political pundits didn’t know he summoned it with the press of a button.

The AP interview was published on Monday, with most news outlets and commentators focusing on its rambling content – Mr Trump’s responses were deemed ‘unintelligible’ no fewer than 16 times.

Mr Trump isn’t the first president to use the button – Barack Obama was pictured with it, and on occasion even brought it off the Resolute Desk into other rooms so someone could be at his beck and call wherever he went.
