NE never does that. They like the slow roast!
Historically they wait for at least a dozen denials over a period of weeks...then present damning evidence.
When NE does this their goal is the total destruction of the public person. Whether GOP or DEM.
They have done it successfully at least a dozen times in modern political history.
And, they do it for the sole purpose of selling the rag at the checkout stand of your local market.
