As a journalist asked if the President was "upset" that he could not get even one member of the opposition on board, the distinctive female voice calmly said: "Sorry, I'm not sure what you want me to change."
She suddenly raised her voice during a discussion on Syria and Iran, which must have been confusing for her.
Siri is Apple's voice command service on iPhones, iPads and its other devices that lets people send messages, make phone calls and perform other functions, as well as being able to converse.
When activated, it can respond to all detected questions and commands, even if they are not meant for it! Such as answering a question at a White House press conference on the Iran nuclear deal.
And with Syria's name also coming up frequently, it was only a matter of time that the soft-voiced help service piped up to lend a hand. Though she wasn't quite sure what she was supposed to do - which she wasn't shy in telling the whole room of journalists.
Speaking out of turn
Press secretary Josh Earnest was being grilled about Barack Obama's failure to gain Republican support when the voice command service made its timely intervention, reports The Independent.
As the assembled journalists burst into laughter, Mr Earnest even cracked a smile on the podium. "That was on time," a woman could be heard remarking in the background.
Reporters joked that it was unclear whether the gadget was speaking on behalf of the White House.
