Republicans roll out new plan to revive the economy by destroying Social Security ...

Mr. Obama has told Republicans he is open to suggestions, and Senator Mitch McConnell of Kentucky, the Republican leader, said his conference would urge Mr. Obama to consider a two-year suspension of payroll taxes to benefit individuals and corporations.

Mr. McConnell said Senate Republicans were intensely interested in the idea, which was presented at their own weekly lunch by Lawrence B. Lindsey, who was President Bush's top economic adviser from 2001 to 2002, and John H. Makin, an economist at the American Enterprise Institute for Public Policy Research.
