As far as I know, Mary Trump stands alone as a close relative wanting to take the President down. (If someone knows of a similar situation, please share). Her tell-all book and constant presence on cable news are a unique phenomenon.
Now Mary Trump is suing her uncle. From CNN:
This is state court, so no self-pardon is possible.New York (CNN)Mary Trump, President Donald Trump's niece, filed a lawsuit Thursday accusing the President and his siblings of committing fraud in order to deprive her of her interests in the family real-estate empire built by Fred Trump Sr.
In the lawsuit, filed in New York state court against the President, his sister Maryanne Trump Barry and the estate of their late brother Robert Trump, Mary Trump asserts that for the Trump's, "fraud was not just the family business—it was a way of life."
The lawsuit accuses her two uncles and her aunt, a retired federal judge, of conspiring amongst themselves and with several other parties, including a trustee appointed to act on Mary's behalf, to give her "a stack of fraudulent valuations" and force her to sign a settlement agreement that "fleeced her of tens of millions of dollars or more."
"Rather than protect Mary's interests, they designed and carried out a complex scheme to siphon funds away from her interests, conceal their grift, and deceive her about the true value of what she had inherited," the lawsuit says.
An attorney for the President, who is being sued in his personal capacity, didn't immediately respond to a request for comment. Representatives for Barry and for the estate of Robert Trump didn't immediately respond to requests for comment.
What is worrisome is how the President will react to another judicial burden placed on his plate. The choice for Trump is stark: Re-election or innumerable court dates. He will, in all probability, either die in prison or die while appealing a prison sentence. Trump knows that if he loses, he has a good chance of losing everything. At a recent rally he said that if he lost we would never see him again. Inside of Trump's narcissistic bubble, the survival of Trump and the survival of the nation are now becoming synonymous.
Trump now will not commit to accepting the results of the election. He wants to sow enough doubt in the electoral process that he can somehow get the election adjudicated in the courts.
So unfortunately I think the result of the suit will be to reinforce within Trump the idea that he must win at all costs.
