If that Gorsuch letter existed, it would blow Ford right out of the water. So why would they keep it under wraps? I highly doubt that Grassley’s primary objective is to get Ford to perjure herself, or to make Feinstein look bad. He wants to get Kavanaugh on the SC. So he would have used that weapon a week ago.
I am not saying it is going to happen, but can you imagine letting Ford testify her cry baby fake story to the whole nation...And then to hit her with unquestionable evidence that she is a fraud. If that happened the other so called witness would loose a lot of credibility just by association.
