A bipartisan pair of senators requested more answers from Supermicro, the motherboard producer that an explosive report said sold equipment to major US tech companies that had been infiltrated by the Chinese government.

Republican Sen. Marco Rubio and Democratic Sen. Richard Blumenthal sent a letter Tuesday to Supermicro's CEO, Charles Liang, asking for more information following a Bloomberg story that reported the company sold motherboards to Apple, Amazon, and the US government that contained microchips implanted by Chinese spies.

In turn, Bloomberg reported, these microchips could have given the Chinese government backdoor access to data on servers where the motherboards were installed.
