Why are protests erupting across the United States?

Protests are occurring nationwide in response to President Trump and Elon Musk's initiatives to significantly reduce the size of the federal government. Hundreds of demonstrators have taken to the streets in cities across America to oppose these controversial changes, with protesters questioning Congressional oversight by asking "Where is Congress?" as the administration moves forward with their plans. The demonstrations reflect growing public concern over the potential impacts of shrinking federal agencies, which according to the description may include mass layoffs of federal workers, including IRS employees, and issues regarding access to sensitive personal data at Social Security.
