Elon Musk was secretly spied on by several agencies in the Biden administration amid fears over his links to foreign powers, according to a bombshell report.

Musk was trailed by government agencies in 2022 and 2023 including Homeland Security and the Justice Department, focusing on foreign nationals visiting his properties, the report says.

Insiders told the Wall Street Journal that the investigations into Musk were primarily looking into whether he was being swayed by foreign powers 'in Eastern Europe and elsewhere', but never progressed to bringing charges.

Sources said the probes highlighted concerns about the number of foreign nationals in Musk's inner circle as he was gaining influence in the US and before he began publicly supporting Donald Trump.

Last year, Musk poured upwards of $250 million into Trump's campaign through a super PAC, the America PAC, raising questions over the unprecedented level of spending in the 2024 election.
