What are the main concerns about DOGE Service staff accessing IRS systems?

The main concerns involve potential access to sensitive taxpayer information through IRS confidential systems. Officials are alarmed about security risks, with attempts to prevent DOGE staff from accessing classified information sometimes leading to confrontations. Legal challenges are being considered to block this access, similar to issues at the Social Security Administration that led to its head resigning. Additionally, the IRS faces threats of mass firings affecting 9,000-10,000 employees, creating further tension between the agency and the White House as systems control becomes a critical point of contention.
