While many Americans tune in to Sunday night's Oscars ceremony, the Trump White House will host its first major social event: the 2017 Governors' Dinner. The black tie affair includes a receiving line, reception, and formal dinner with the First and Second Couples. It is timed to correspond with the National Governors Association's winter meeting in Washington each year. "The Governors' Dinner is one of the most important social events held at the White House each year," said Laura Dowling, who was the chief White House floral designer for six of President Obama's eight years in office.
