A prime example is the case against former Chief of Staff Mark Meadows for interference in the Georgia vote count. His attorneys filed a frivolous motion to remove his case to federal court, on the ridiculous basis that he was performing his duties as Chief of Staff when he interjected himself into the Georgia election process.
This was a meritless claim on so many levels that one hardly knows where to begin. He testified that he just happened to be in Georgia visiting his kids in college, and decided to stop in to observe the vote-counting process. Totally absurd, as the vote-counting is by law a state function and the federal government has no legitimate role in it, and he was not even permitted in the room under Georgia law.
And the Hatch Act prohibits federal employees from involvement in political activity, so by definition it could not have been a part of his duties.
Faced with a loser of a case, a good attorney will advise a client to cut his or her losses and work out a deal to resolve the case. The Trump lackeys either have poor attorneys or are too stubborn to listen to them.
