UPDATE: Another Republican, Darrell Issa of California, will announce he is joining Mack in his call for Geithner to resign as Treasury Secretary.
Rep. Connie Mack, (R-Fla.), called Wednesday for Treasury Secretary Timothy Geithner to resign or be fired in the wake of the AIG bonus scandal.
"Well before Timothy Geithner became Secretary of the Treasury, he was working hand-in-hand with AIG and other financial institutions to provide them hundreds of billions of dollars of taxpayer money as one of the key architects of the financial sector bailout. I was outspoken against the bailouts then, and I'm even more outraged now.
"I've had serious concerns about Secretary Geithner from the moment he was nominated. In the months since, he has shown us time and again why he was the wrong choice for this critical post.
"This week's news on the AIG bonus scandal is but the latest fiasco under his watch and he has lost the confidence of the American people.
"Quite simply, the Timothy Geithner experience has been a disaster. The Treasury Department is in disarray. Taxpayer dollars are being wasted. America's economy hangs in the balance. America needs and deserves a Treasury Secretary who can truly lead us forward.
"Timothy Geithner should either resign or be fired for the good of the country, and President Obama should nominate a new Treasury Secretary with the experience and leadership skills America deserves."
According to USA Today's On Politics blog, no other members have called for Geithner's resignation yet.
His spokeswoman, Stephanie DuBois, says that "to the best of my knowledge" Mack is the first member of Congress to do so.
