I agree that something has to be done - Mueller is so going to make things up.
IMO a special counsel to investigate Mueller’s team would be best. Similar to your idea but with a focus on activities of Mueller’s team instead of muh russia.
There is the underlying current of obstruction by Mueller’s team intended to mask previous crimes. I’d like that to be stopped. And, if Mueller’s team does nothing wrong, I’m fine with them. My worry is that they’re a)ginning up charges to bring down and administration and b)covering up crimes done by political allies from the last political administration.
Yeah, an independent counsel charged with investigating Mueller’s independent counsel. Who on the left will object? We just need to investigate....
