Facebook's CEO visited the Ford Rouge Assembly Plant in Dearborn on Thursday.
Mark Zuckerberg posted pictures on his own Facebook page about the tour. He wrote in a post, "It's my first time in Michigan, and my first stop was at the Ford Rouge Plant. I played a very small part in assembling some new F-150's on the line by adding antennas, cleats and drilling screws."
Zuckerberg said he even signed the inspection sticker on one of those pickup trucks.
