Mike Ward was a veteran reporter at the Houston Chronicle. But when editors got a tip that some of the sources quoted in his stories could not be verified, they launched several internal investigations that led to his resignation this month and a very open review. I spoke to Chronicle interim editor Stephen Riley about how it was done. I also chatted with Lynn Walsh from the Society of Professional Journalists about the issue and how she is involved in helping newsrooms provide such open connections to readers through a great new program.
