Missouri Democratic gubernatorial candidate Chris Koster is calling off debate negotiations with opponent Eric Greitens unless the Republican nominee releases his tax returns for the years 2012 through 2015.
Koster's campaign on Tuesday sent a letter to Greitens' campaign manager, Austin Chambers, noting that Koster released his own returns Thursday. The letter says Greitens has promised to release his returns once Koster did so, but so far has not.
The letter calls on Greitens to release his personal returns and those for Eric Greitens LLC by Thursday. The letter says the release of taxes is an "absolute conditon" for continued discussion of a debate on Oct. 14.
