Trump has a red button on his desk that doesn't launch nukes, but instead orders a Coke.
In an interview with The Associated Press, Trump revealed the purpose of a "red button" on his desk, which apparently is used to summon a butler with a Coke for the president.
“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," the AP reported.
