President Donald Trump hosted a dinner for European business leaders on Thursday, his first night at the World Economic Forum in Davos, Switzerland.

At the start of the event, each of the guests described what his or her company does, and most of them complimented Trump on the passage of the GOP tax cut bill.

Notably absent from the list were Treasury Secretary Steven Mnuhcin and Commerce Secretary Wilbur Ross, both of whom traveled to Davos this week as part of the U.S. delegation.

CNBC asked a White House spokesman why Mnuchin and Ross did not attend the event, and we will update this story with any response.

Here's the guest list, according to the White House.
