Haven't officially heard anything but I extremely doubt it will happen because the Social Security Trust Fund needs this money - that's where it goes; not to the General fund.
President Reagan created the tax in 1983 but only on 50% of it. Think of this as the 50% that your employer contributed which wasn't taxed while you were working and contributing (employee & employer). That was the Social Security Amendment of 1983 which saved the financial woes of the Trust Fund it was going through back then.
A provision of the 1993 Omnibus Budget Reconciliation Act raised the Social Security tax rate from 50% to 85% for households in a higher income bracket. The act was Democratic President Bill Clinton's first budget and marked the highest peace-time tax increases on high-income earners in U.S. history up to that time, according to the University of California, Berkeley.
Biden, a Congressman at the time, voted to pass the 1983 amendments, according to records maintained by the SSA. GovTrack, a government transparency website, recorded Biden's yea vote on the 1993 Act.
