President Barack Obama got in a little bit of hot water over a cup of coffee.
The White House Instagram showed a video of Obama exiting Marine One, the presidential helicopter. Obama offered a salute with a cup of coffee still in his right hand as he passed by a Marine standing guard.
Some people tweeted the "Starbucks salute" was a sign of disrespect for the Marines.
Other people said the matter was trivial.
See the video for yourself.
