President Trump on Tuesday announced that he has asked SpaceX founder Elon Musk to “go get” two NASA astronauts who have been aboard the International Space Station since June awaiting a return trip to Earth.

Ali Velshi explains how, amid reports of tension between Trump and Elon Musk, the president seemed to suggest sending the billionaire to space.

The founder of SpaceX said President Trump had asked his company to return two astronauts aboard the space station to Earth “as soon as possible.” NASA said it would do that “as soon as practical.”
