Not to be confused with the Governors Ball after the 89th Academy Awards in Hollywood, Sunday night was also the date of the annual Governors Ball at the White House.

The White House gathering was the first major social event of President Donald Trump's administration, according to the Associated Press. The president toasted the nation's governors, welcoming 46 of them and their spouses to the black-tie ball.
