In an emailed statement addressing the president’s order, Biden said that such a move would “undermine the entire financial footing of Social Security.”

The presumptive Democratic nominee said that unlike the 2012 payroll tax plan put forth by the Obama administration, Trump’s executive order does not appear to include “protections or guarantees that the Social Security Trust Fund will be made whole.”

“He is laying out his roadmap to cutting Social Security,” Biden said. “Our seniors and millions of Americans with disabilities are under enough stress without Trump putting their hard-earned Social Security benefits in doubt.”

Employees and employers each pay Social Security payroll taxes of 6.2 percent of wages and Medicare payroll taxes of 1.45 percent of wages. One of Biden’s tax proposals would increase the payroll tax rate for people making over $400,000.
