In case people forget (I did), the House didn't award the Cognos contract, the Governor did. It's pretty tough to pin someone for wrongdoing when that someone didn't award the wrongdoing in the first place. More on that here.
Anything else that's been pushed? Guilt by association; yellow journalism.
The wrongdoings should be investigated, of course, but people should not make assumptions or accusations on anyone potentially involved with that wrongdoing, because we just don't know enough about what happened to say whether or if anyone did anything wrong to begin with.
