The shooting in Pennsylvania that left former President Donald Trump bleeding from the ear is making Elon Musk rethink his security protocols.

"You better beef up your security too @elonmusk," an X user called Whole Mars Catalog tweeted at Musk on Saturday night, after the shooting.

"Maybe it's time to build that flying metal suit of armor," Musk replied.

lan Miles Cheong, a Musk friend and common fixture on X also asked Musk to "triple" his protection, writing on X: "If they can come for Trump they will also come for you."

"Dangerous times ahead," Musk wrote in response to Cheong. "Two people (separate occasions) have already tried to kill me in the past 8 months. They were arrested with guns about 20 mins drive from Tesla HQ in Texas."
