The Democrats need more time to destroy evidence.
They need more time to manufacture witnesses.
In 1987, I was the director of an important, federal/state funded program somewhere in the Northeast.
One fine day, an advocate/organizer called and asked if I could testify before a Senate committee the next day. The advocate was at that time quite well-known, but I was not.
All I had to do was tell the story of a patient who was being discriminated against in a certain way.
I was offered lunch with the Chairman, a news conference after, and the inside track to more $$ for my program.
The problem was, none of my patients were being discriminated against to fit the scenario, and I said so.
"Oh, no worries", I was told. "We have a script".
Since that day (OMG 30 years ago!) I have never taken a single word spoken in a Senate or House committee seriously.
The Dems need a delay to find their Anita Hill, or equivalent. Somebody who tried to give Sessions tickets to "Django Unchained", only to have him refuse to go. Or whatever. The lie is unimportant, the coverage of the lie is critical.
If the GOP gives them their week, they will find someone to testify, count on it.
