President Donald Trump spoke at a rally in Harrisburg, PA to mark his first 100 days in office on Saturday.

The president has opted out of attending the 2017 White House Correspondents' Dinner, a decision he announced weeks ago.

The dinner will air live from Washington later on Saturday. Comedian Samantha Bee is also hosting a gala for the press Saturday evening, the Not the White House Correspondents' dinner, which will be broadcast at 10 p.m. on TBS.
