In the 2019 book, Team of Vipers, written by former White House aide Chris Sims, the use of the button was explained in more detail. Chris described how Donald Trump would suddenly press the Diet Coke button, leaving his guests in a slight state of panic before a butler would enter with the drink on a silver platter.

Donald Trump had used the valet button to order Diet Coke beverages between 2017 and 2021 - during his first presidency - but then Joe Biden had it removed when he came into power

Joe Biden’s blue rug was swapped for Trump’s neutral-coloured one as part of a switch from the outgoing president’s belongings to the incoming one’s, and Trump’s infamous red Diet Coke button reportedly was back in place by as early as mid-afternoon on inauguration day.

The Wall Street Journal reported the valet button, which the president used to order Diet Cokes during his first term, already had been reinstalled Monday even before he was sworn into office. Another story said he was reported to drink around a dozen Diet Cokes a day in 2018, though it is unknown if he maintains that habit.

Donald Trump's beloved soda button is back and ready for four more years of thirst quenching with just a push.

Donald Trump has had a number of changes made to the Oval Office upon his return to the White House, including the reinstallation of a button which automatically requests a glass of Diet Coke
