It was Ronald Reagan in the 1980's.  "Under President Ronald Reagan, the Omnibus Budget Reconciliation Act repeals Carter's community health legislation and establishes block grants for the states, ending the federal government's role in providing services to the mentally ill.  Federal mental-health spending decreases by 30 percent."  https://www.congress.gov/bill/97th-congress/house-bill/3982.  Not the liberals.
