Those "lawsuits" are politically motivated.

The Dems would be far better off putting together policies that people would vote for (e.g., Bernie Sanders' platform).  But they're wasting their time on things the majority of voters don't care about.  Which is why they will lose big time, and Trump will continue to win.

Trump is a businessman, not a lifelong politician.  He's bound to make some small mistakes in the beginning as he learns the rules, just like anyone learning a new job.  But nothing Trump has done is criminal or worth investigating.
