If the US government shuts down, non-essential government functions will freeze, affecting many services and federal employees. Critical agencies like the FBI, CIA, air traffic control, and military will continue operating, but many federal workers will be furloughed or work without pay until funding is restored. Social Security, Medicare, Medicaid, and veterans' healthcare will continue, though some delays may occur. National parks and museums may close, and airports could see longer security lines and travel delays due to unpaid air traffic controllers and TSA workers. Economic impacts include lost paychecks for millions of federal employees and potential layoffs, which could slow consumer spending and disrupt government operations nationwide until a funding agreement is reached.
