Don't miss Rubio's EXCLUSIVE, hour-long "Hannity" interview tonight at 10p ET


Sen. Marco Rubio (R- FL) is set to announce that he is running for president in 2016. 

Rubio is planning to make the formal announcement later today in Miami to a group of supporters after disclosing the information to donors on a conference call earlier today.

He will be the third Republican senator to enter the race for the White House in 2016. The only Democrat to enter the race thus far is Hillary Clinton, who announced yesterday that she is running using a video posted on her new campaign website.

David Drucker, of The Washington Examiner, weighed in on "Happening Now," stating that it was originally thought that Clinton could step on Rubio with her announcement. Drucker said that instead Rubio might actually have "a bigger stage."

"At least for today, he is going to be the Republican voice of the opposition to the president's policies and to Clinton," Drucker said. "It gives a great contrast for a 43-year-old up-and-coming Republican who's asking voters to join him for a new generation of leadership versus Hillary Clinton, 67, a voice from the past."  

Drucker said that Republican primary voters are generally concerned about the president's foreign policy and that Rubio's fluency on the topic will give him the chance to overcome the challenge.
