Minnesota Gov. Tim Pawlenty today said there's no need for more state investigation into ACORN because, "We're doing it."

U.S. Rep. Michele Bachmann, a Republican and longtime critic of ACORN, said Monday that the state needs a special investigator into all issues ACORN.

But Pawlenty, a fellow Republican and no slouch when it comes to ACORN bashing, said that won't be necessary.

"That is being done and has been underway for several weeks," Pawlenty said. When he blocked all state funding of ACORN stopped last month, he also asked the Minnesota Management and Budget department  to review ACORN's activities and funding. ACORN does not currently receive any money from the state.

Pawlenty also brushed aside suggestions that ACORN's involvement in Minnesota's 2008 election makes the validity of  U.S. Sen. Al Franken's close election more tenuous.

"On those matters, we need to see evidence," Pawlenty said. "Nobody has brought to my attention a specific instance of voter fraud by ACORN. I know there are concerns or theories in that regard but we as far as I know we have not been presented with the evidence. If there were such evidence, it probably would have been presented in the Coleman v. Franken lawsuit. "

The governor's in good company on his call for evidence before doubts. Fox's Bill O'Reilly said, even though he "despises" Franken,  "I don't know if it's fair" to cast doubt on Franken's election because of any ACORN involvement. But O'Reilly also said he wants Pawlenty to order a review of any voters ACORN registered in Minnesota.
