FreedomWorks PAC, the political arm of Dick Armey's activist operation, is expected to endorse lawyer Mike Lee in his long-shot GOP primary challenge to Utah Sen. Bob Bennett.
A source familiar with the group's plans said the endorsement is likely to come at an afternoon press conference.
Winning support from FreedomWorks will boost Lee's effort to brand himself as a tea party candidate, because Armey's organization is looked to as an important organizing hub by tea party activists across the country.
Lee also has strong links to the conservative establishment, having clerked for U.S. Supreme Court Justice Samuel Alito and served as a top lawyer to former Utah Gov. Jon Huntsman. His father, Rex Lee, was U.S. solicitor general.
