Where to watch the White House correspondents' dinner on TV and online

Another year, another White House correspondents' dinner. You can witness all the weirdness that is this annual Hollywood-Washington mash-up: President Obama performs a stand-up routine. A celebrity host (this year, "Saturday Night Live's" Cecily Strong) makes fun of everyone. Spot various actors from "Scandal" with politicians and wondering what on earth they could possibly be talking about.
