From The Hill:

Rep. Michele Bachmann (R-Minn.) on Tuesday called for a “strong investigation” into a wide variety of non-profit organizations in the wake of allegations of political corruption in ACORN.
Bachmann, who has been an outspoken critic of ACORN, said that a broader investigation is needed of other non-profit organizations because they could be using federal funds to influence the outcome of elections, like ACORN did.
“We need a strong investigation into non-profits,” she said in a conference call with conservative bloggers hosted by the Heritage Foundation. “No political party should be funded through a quote non-profit.”
“Without [government] money they would not be in existence,” she added.
