Charles Kushner, Jared's father, pled guilty to illegal campaign contributions, tax evasion, and my personal favorite, witness tampering, where he hired a hooker to screw his brother in law, video taped the sex act, sent it to his sister and used it to intimidate her from testifying against him.
Jared Kushner, like Hunter Biden, has been the beneficiary of his father's success. Despite not having the test scores or grades to get into an elite University, Jared was accepted by Harvard, perhaps America's most prestigious University. The mediocre student who accomplished nothing professionally currently serves as a senior advisor to the President.
The Kushners have deep connections with foreign nations, namely Israel - the Kushner family foundation has donated piles of money to charities and politicians in Israel and Netanyahu has literally slept in Jared's bed when he visisted the US. Do you think Jared may have a vested interest in ME policy due to their pre-existing relationship? It was widely reported that US intelligence (whatever that's worth) was concerned that Israel, China, United Arab Emirates, Mexico, and perhaps other nations tried to manipulate Jared b/c he's a moron and his family has finanical interests everywhere. He's had some interesting interactions with Saudi Arabia as well.

I posted the article from The American Conservative b/c I'm not trying to do a left wing smear of the Kushner family. This family uses money to influence policy. It's what they do. It's their business. That alone should prevent Jared from having any influence in the WH. Even if he came from a clean family, what has he done to suggest he should be a senior advisor to Trump? He married his daughter?
