A bipartisan group of six Missouri state senators is calling for a legislative investigation of Republican Gov. Eric Greitens.

A resolution filed by Kansas City Democratic Sen. Jason Holsman asks for an investigation of campaign use of a donor list from a charity that Greitens' helped found and that wasn't originally listed in campaign finance reports. Greitens' campaign was fined for failing to report use of the donor list. The charity helps veterans transition to the private-sector through volunteer work.

The senators also want to review a nonprofit that promotes Greitens' agenda and is not registered as a lobbying entity. The resolution also claims there is coordination between the nonprofit and the governor's office.

A spokesman for Greitens did not immediately respond to a request for comment Tuesday.

Holsman is joined by another Democrat and four Republicans.

Greitens' spokesman Parker Briden released the following statement in response:

We put out a call for a special session to protect lives and the health and safety of Missourians, and this is the response from these politicians? They’re angry that the Governor is shaking up Jefferson City and won’t accept their excuses for failure any longer. Temper tantrums from career politicians don’t bother us. It’s just more evidence that Governor Greitens is an outsider who is doing what he said he would do: taking on politicians in both parties to get results. When career politicians are whining, Missourians are winning.
