The only possibility is that the PR firm would have worked with Instapundit or Powerline, but I don't think that's likely either. For one thing, Insta is based in Tennessee. and Powerline is in Minnesota. Secondly, they have never (as far as I know) mentioned working with PR firms (since they prefer openness, I believe them).
This self-serving lie by a PR firm plays into DUers conspiracy theories. The PR firm is hoping conspiracy-minded Dems will believe their story and lend it credibility.
