Senate Majority Leader Harry Reid (D-Nev.) plans to introduce a compromise measure Monday to extend the payroll tax cut, according to a key Senate Democrat. “Majority Leader Reid called me yesterday and said he will propose tomorrow a compromise plan to extend the payroll tax cut,” Senate Budget Committee Chairman Kent Conrad (D-N.D.) said on “Fox News Sunday.” “He will offer it at that point – I don’t think it’s probably in my purview to announce his plan – but he indicated to me it will be paid for. It will be paid for in a serious way.”
