Trump dines with John Kelly, Steve Mnuchin, Wilbur Ross at Trump Hotel in DC

The dinner comes one day after Kelly was named as the new WH chief of staff.

The president arrived at the luxury hotel around 8 p.m., and left after about two hours. Once inside the hotel, he was met by a throng of people snapping photos of him on their smartphones. As he departed the hotel, Trump waved to onlookers, many of whom cheered.

Social media users inside the hotel posted photos of the presidential posse sitting in a banquette at the property's steakhouse, BLT Prime by David Burke. In one photo, Trump is seated next to Kelly and Linton.

Prior to arriving at the hotel, Mnuchin, Ross and their wives were spotted at the South Portico of the White House waiting for the president.
