If I may refine your good comments a little...
She sent here letter to her Congresswoman and Senator before Trump formally nominated him as it was almost certain in the last week he was the nominee. She was preparing to do this because he was named as likely. Then the Democrats and the WaPo (who also had it) both held it to make better chaos and theater.
I bet there were smears placed with various ‘news’ organizations ready to go for each of the 4 judges in the short list.
It was just a matter of pushing the one related to the actual nominee. That would explain the ‘but she made the claim before Brett was even nominated’ excuse.
Someone should do a little investigative work into that.
