I don't know if the judge has been involved at the beginning, but I don't think the Trump team thought there was an issue until the judge ruled against him repeatedly, in ways that some would consider to be judicial misconduct.
However, I don't know why they haven't filed a motion for recusal. I think they should have done that, and let it speak for itself -- rather than Trump complaining publicly.

I agree.
