Sen. Ron Wyden (D-Ore.) is looking for answers on Trump son-in-law Jared Kushner’s infamous investment business that he has steered since leaving years of service on Trump’s political team and in the White House.

The company has raked in large sums from foreign sources like Saudi Arabian authorities, alongside others. And now, some of the details that Wyden wants get right to Kushner himself.

“Please provide how much compensation Jared Kushner has received from Affinity for each calendar year from 2021 to 2023. Please describe in detail how much Kushner was paid annually by Affinity in salary, bonuses, other compensation, dividends and any other distributions associated with equity interest in Affinity,” says a bullet point in the Senate committee leader’s letter to another leading figure at the company. There’s a lot more to Wyden’s requests, and you can see the rest right here.

This time around, Kushner does not appear to be directly participating in his father-in-law’s political operation as Donald seeks another term as president and remains on track to secure Republicans’ presidential nomination next month. Being a son-in-law is still a close relationship, and there is precedent for looking at the financial entanglements of some family members when examining possibilities that a public official is ensnared in conflicts of interest. Kushner is married to the former president’s daughter Ivanka, who also held an official role in her father’s presidential administration throughout his time in office.

Donald has his own apparent Saudi financial connections, as his properties have repeatedly hosted events for LIV Golf — a relatively new league that has apparently gotten funding from the same source in Saudi Arabia: its Public Investment Fund, where Crown Prince Mohammed bin Salman is a key figure. He is also widely accused of involvement in the murder of journalist Jamal Khashoggi in 2018 in Turkey.
