Interesting. Can you link to where the claim was made and where it was refuted?
All that I know about her is that she defeated that duplicitous monster Hackett and that she called Murtha a "coward" on the House floor.
I found an article where Chabot and Schmidt joined together in voting "present" in a resolution honoring the Steelers and an earlier one where Chabot defended Schmidt's Hackett remarks. Searching on Tancredo is problematic.
Where have you been? Schmidt's false claims of endorsements from Chabot and Tancredo are all over the place.
The links below discuss Mean Jean's lies regarding both the Chabot and Tancredo non-endorsements.
