AP NAtional says it was AP Regional Wisconsin.
AP Regional Wisconsin says it was AP National.
Neither Office will give out the name of the reporter.
AP National 212-621-1600
AP Milwauakee 414-225-3580
Why would any other news organization by anonymous news? Which is what this amounts to when AP refuses to put a byline on a story and/or disclose the name of the reporter.
Imagine that....
Accountability is truly their touchstone.
