Nope, that won't fool anyone. Murphy spoke in his DHS capacity, and addressed suppression of information that happened there and with other agencies he had contact with.
And the clusterfuck comment is irrelevant to the point that was specifically made in regard to pressuring agencies to alter intelligence conclusions, or suppress information in order to promote Trump's campaign platform.
When you do that, you are a traitor to democracy, a system that requires honest reporting of the facts.
