Why is a federal employee union filing a lawsuit against Elon Musk and the White House?

The National Federation of Federal Employees is filing a lawsuit to block Elon Musk and the White House Department of Government Officials/Efficiencies from accessing sensitive IRS records. This legal action appears to stem from concerns about allowing access to private tax data to political appointees or external advisors. The lawsuit has generated significant attention, with the news anchor noting increased social media chatter about the case. This action reflects broader tensions about the appropriate boundaries between government transparency initiatives and the protection of sensitive taxpayer information.
