On June 13, 2016, despite his previous statements that he would not run for re-election to his Senate seat, Rubio "seemed to open the door to running for re-election," citing the previous day's mass shooting in Orlando and how "it really gives you pause, to think a little bit about your service to your country and where you can be most useful to your country." On June 22, 2016, Rubio announced that he would seek re-election to the Senate, reversing his pledge not to run.
