WASHINGTON, Jan. 4 (UPI) -- Grassroots Tea Party movement leaders are saying Republicans may pay a price for their votes on the "fiscal cliff" deal this week.

Amy Kremer, leader of the Tea Party Express, said Thursday she was "outraged" about the deal, reached by Senate Minority Leader Mitch McConnell, R-Ky., and Vice President Joe Biden that allows tax rates on upper income earners -- families earning more than $450,000 and individuals earning more than $400,000 -- to expire while making permanent tax breaks passed during President George W. Bush's administration for earners making less than that, CNN reported.
