What is the biggest threat to Social Security according to Martin O'Malley?

According to Martin O'Malley, the biggest threat to Social Security is the potential that Elon Musk and Donald Trump could drive 10,000 people out of the agency, which could interrupt vital benefit checks. This concern is heightened because Social Security is already operating with staffing at a 50-year low due to Republican budget cuts. The agency is particularly vulnerable as it now serves more active beneficiaries than ever before due to the aging baby boomer population. With half of all seniors living alone depending entirely on Social Security, O'Malley emphasizes the fragility of the system and the serious consequences that further staff reductions could have on millions of beneficiaries.
