As previously reported, Senator Grassley had asked ACORN for information to investigate whether they are at risk for losing their tax exempt status because of voter fraud allegations. ACORN has yet to supply any response to that letter, and Grassley has now contacted the Internal Revenue Service. According to BNA, (subscription required) Grassley has now asked the IRS about its plans to investigate ACORN. You can read the letter Grassley sent to the IRS here. In his Nov. 8 letter to IRS, Grassley asked IRS "to describe any enforcement action it might consider," pointing out that four members of the group recently were indicted for allegedly submitting false voter registrations in Kansas City, Missouri.
