Working for Feinstein is one thing (bad enough on its own) but it would be nice to know who is paying. Follow the money. It always leads to interesting places.
The answer to that is in Kavanaugh's opening statement:
This whole two-week effort has been a calculated and orchestrated political hit, fueled with apparent pent-up anger about President Trump and the 2016 election, fear that has been unfairly stoked about my judicial record, revenge on behalf of the Clintons and millions of dollars in money from outside left-wing opposition groups.
You can bet that the money in question is laundered Soros money.
