President Donald Trump is holding a rally in Harrisburg, Pennsylvania today in celebration of his first 100 days as President. The rally looks like it's going to have a big attendance, with many people lining up for hours ahead of time so they could get a seat. As with his previous rally, the details for this one were posted on his presidential campaign website. The rally begins at 7:30 p.m. Eastern, but people were lined up hours earlier at the PA Farm Show Complex & Expo Center. In fact, John shared this photo with Heavy, showing how the Expo Center was already getting packed with people even an hour before the rally began. Trump is attending this rally instead of attending the traditional White House Correspondent's Dinner, which is happening tonight too. Trump said during his speech that the crowd size broke the all-time record for the arena.

We'll be adding more photos from Trump's rally as they're available. (Photo by John)
