WASHINGTON (AP) — The bad economy is worsening the already-shaky finances of Medicare and Social Security, draining the trust funds supporting them faster than expected and intensifying the need for Congress to shore up the massive benefit programs, the government said Friday.

Both Medicare and Social Security are being hit by a double whammy: the long-anticipated wave of retiring baby boomers and weaker-than-expected tax receipts, according to the annual report by the trustees who oversee the programs.

The Medicare hospital insurance fund for seniors is now projected to run out of money in 2024, five years earlier than last year's estimate. The Social Security trust funds are projected to be drained in 2036, one year earlier than the last estimate. Once the trust funds are exhausted, both programs can only collect enough money in payroll taxes to pay partial benefits, the report said.
