If Dr Ford is not willing to testify, why delay the vote?

The White House and the Republicans on the Senate Judiciary Committee have all come out and stated she should be heard.

They've delayed the vote and invited her to testify on Monday.

She is refusing to testify.

And before you say ' the FBI should investigate '

Consider:
1. Sexual Assault is a State crime, not a Federal Issue.
2. Even if it was, there's nothing to investigate:
A 35 year old claim where the accuser does not remember where or when it happened and there's no evidence to examine.
3. Kavanaugh has already passed SIX FBI background checks.

First the warranty me for free, now they are asking me to pay?

So awhile back when my tire grew a budgle on the sidewall, i got it warranty by ford to replace it for free. After 4 months, i get a mail today saying the warranty was denied by Michelin, and that i need to pay for the tire.
should i just ignore them? I don't think they can do much since i already have a receipt showing they did it for free back then. Its like them telling me to pay for their mistakes. They even had the car for a whole week and said a tire inspecter came and look and said its good to be replaced for free.
