I found these stories on the blogs of conservative Republicans. They are not going to let Obama weasel out of the consequences of his incompetent Cabinet picks.

Marsha Blackburn
Representative Marsha Blackburn posted about Geithner on her blog.
Excerpt:
Yesterday Congressman Marsha Blackburn (TN-7) appeared on The Fred Thompson Show and called on Secretary of the Treasury Tim Geithner to resign.
“I think that he has caused more problems than he has solved,” Blackburn said on the nationally syndicated radio show. “I think he needs to go and it doesn’t matter if the President wants to remove him or he wants to submit his resignation but Secretary Geithner needs to go.”
Audio of Blackburn on the Fred Thompson radio show is here: short clip, long clip).

Jim Demint
Jim Demint calls for the firing of Geithner in this post on his blog:
Excerpt:
During an interview with FOX Business, Sen. Jim DeMint (R-S.C.) discusses Americans’ outrage with AIG bonuses and government bailouts. DeMint calls upon President Obama to fire Treasury Secretary Timothy Geithner, saying that Americans have lost confidence in him because he clearly “has lost his ability to operate” and deal with America’s current economic crisis.

John Shadegg
In addition, Representative John Shadegg had a post on his blog.
Excerpt:
“How could Geithner have been so intimately involved in the AIG bailout, head of the New York Federal Reserve when the Reserve was informed of the bonuses, head of the Treasury when the department asked for the provision that helped secure these bonuses, and supposedly one of the greatest experts on Wall Street today – and not have known about them?
“Sadly, it appears that Secretary Geithner is either dishonest or incompetent.
“Perhaps the Senate should have paid more attention to Geithner’s tax errors after all.”
We need to embarass Obama for nominating this incompetent tax cheat.
