Marco Rubio Announcing 2016 Presidential Bid

It's (pretty much) official: Marco Rubio is announcing his 2016 presidential bid Monday!
The Florida Republican Senator tweeted a link to IJReview's behind-the-scenes photos from Rubio's "planned presidential announcement," reportedly taking place at 5:30 p.m at a Miami rally.
Rubio, 43, posted a countdown clock of his own. Additionally, a campaign source tells NBC News that Rubio told donors on a Monday morning call he is "uniquely qualified" as a spokesperson for his party.
