Scott Brown writes in a letter to Chris Dodd and Barney Frank:
I am writing you to express my strong opposition to the $19 billion bank tax that was included in the financial reform bill during the conference committee. This tax was not in the Senate version of the bill, which I supported. If the final version of this bill contains these higher taxes, I will not support it.
More on the $19 billion tax here.
Update: Congress is going to try to scrap the tax. A Senate aide tells Daniel Foster:
It appears the conference will be reopened, possibly as early as this afternoon, to look at an “alternative” funding mechanism.
