SpaceX CEO and notorious Twitter troll Elon Musk jokingly accused President Joe Biden of “sleeping” after a follower noticed the president failed to acknowledge the efforts made by four civilian astronauts who raised money for St. Jude Children’s Research Hospital.

The SpaceX Dragon capsule’s two men and two women launched into space Wednesday and returned to Earth Saturday following three days in orbit. Musk helped raise more than $200 million for St. Jude from the all-civilian SpaceX mission and was even congratulated by rival space voyager Jeff Bezos. However, the president did not appear publicly to acknowledge the successful mission.
