The moment was so fleeting, it could have been missed in a millisecond.
At a White House event Wednesday, President Donald Trump thanked Apple CEO Tim Cook for his efforts to bolster the American workforce.
"You've really put a big investment in our country," Trump told Cook, who was sitting to the president's right.
And then Trump continued: "We appreciate it very much, Tim Apple."
Cook didn't appear to register the mistake at all. To Trump's left, his daughter, White House adviser Ivanka Trump, blinked and glanced ever-so-briefly downward. But the president kept speaking without missing a beat.
