That’s one of several questions Sen. Elizabeth Warren (D-Mass.) and Sen. Tammy Baldwin (D-Wis.) posed in a Thursday letter to Goldman Sachs CEO Lloyd Blankfein. The letter notes Trump’s cabinet is full of Goldman Sachs alumni. Gary Cohn, for example, left Goldman to head up President Trump’s National Economic Council.

“Mr. Trump released two executive orders with Mr. Cohn at his side, both from the Wall Street wish list: one promised to roll back Dodd-Frank rules put in place after the 2008 Financial Crisis, and another put in place a process that could eliminate new requirements that investment advisers act in their clients’ best interests,” the two Senators wrote.

Not only would the Senators like their questions answered by Feb. 22., but they would also like records of communication between Cohn and Goldman Sachs employees since he began working in the government. You can read the letter in its entirety here.

Earlier this month, Warren and Baldwin sent a letter directly to Cohn, asking the advisor to immediately pay taxes on his estimated $285 million payday gained upon leaving Goldman.

As far as Goldman is concerned, though, Goldman Sachs has not influenced President Trump.

“We’ve had no involvement in the drafting of any executive orders,” a spokesman for Goldman Sachs wrote in an email.
