If you are talking about Wells Fargo, you are not exactly correct. Wells has not directly given ACORN the kind of money Bank of America has or promoted it. But in 2007 Wells adopted a set of "responsible lending principles" (link here) for its mortgage operations as a direct result of threats and constant protests by ACORN, and it did join ACORN's "advisory council" which is a shakedown operation to get $100,000+ in grants from lenders in return for it not protesting at the lenders' offices.

That's not very ACORN friendly
