Elon Musk has gained a concerning level of power over US national security | Robert Reich

Under 18 US Code Section 871, threatening a president or vice-president or inciting someone to harm them is a felony that can result in a large fine and up to five years in prison.

Yet even as Musk posted a potential death threat against the sitting commander-in-chief, his multiple defense contracts with the US government have given him access to highly sensitive national security information.

Musk has reportedly gained national security clearance notwithstanding his admitted use of drugs, not necessarily illegally: the tech billionaire, who says he has submitted to random drug testing at the request of the government, has smoked weed in public and also uses ketamine (for which he claims to have a prescription).

Apart from the drugs, when was the last time the US government gave access to sensitive national security information to someone who posted a potential death threat against the president and vice-president?

Underlying this is a broader question: when in history has one unelected individual held such sway over US national security?

SpaceX and its Starlink system have become strategically critical to the American military. Starlink is providing connectivity to the US navy. The US space force signed a $70m contract with SpaceX late last year for military-grade low-Earth-orbit satellite capabilities. According to Reuters, the National Reconnaissance Office, which oversees US spy satellites, has a $1.8bn contract with SpaceX.

Meanwhile, Nasa has increasingly outsourced spaceflight projects to SpaceX, including billions in contracts for multiple moon trips and $843m to build a vehicle that will take the International Space Station out of commission.
