[Elon Musk Warns Democrats: Will Retaliate If Investigated Along with His Companies] Elon Musk has vowed to retaliate if Democrats gain control of one or both chambers of the U.S. Congress and attempt to use oversight powers to investigate him. Previously, Musk responded to a report stating that Democrats have been considering ways to investigate the billionaire and his companies, including Tesla (TSLA.O) and SpaceX (SPCX.O). Musk posted on his social media platform: 'Those who live by the sword shall die by the sword.' 'Those who trouble me should understand that I will expose the true masterminds behind the scenes and target them directly, not just their puppets.' Musk has been a major donor to Republican candidates and has collaborated with the Trump administration through the 'Department of Government Efficiency' (DOGE).
