He is a jerk. He has no concern for his 3 daughters or the nieces and nephews who lost their father, Beau. After breaking it off with Beau’s widow, he went to California and married a young woman after knowing her 10 days.
In the meanwhile, while cavorting with these women, he was also raking in the money from Ukraine - money laundered through a Ukraine energy company - but is likely really US taxpayers’ money.
He is not a man of honor or decency. Joe ought to disown him and set a better example for his grandkids.
I believe if you look past the facade, you'll find that it runs in the family.
