The annual gathering not far from the White House that brings together journalists, government officials, politicians and media personalities for what’s usually an evening of light-hearted banter and celebrity gawking has begun.

Often referred to as “Nerd Prom,” the annual White House Correspondents’ Dinner is being hosted this year by entertainer, comedian and late-night TV talk-show host Conan O’Brien.

Here are some images from the event so far:
