A senior Republican predicted Tuesday that Congress will pass legislation this year to overhaul the nation’s pensions system and suggested that the idea of linking pensions to the politically unpopular drive for Social Security reform may have to be shelved.

Rep. John Boehner, R-Ohio, chairman of the House Education and the Workforce Committee, said the House would probably act before the end of October on legislation to better protect the retirement benefits of millions of Americans and ensure that failed pension funds don’t result in a massive taxpayer bailout.
