Marco Rubio's going up on the TV air in Florida ahead of the Aug. 30 primary in which the Republican senator faces a challenge from Sarasota developer Carlos Beruff.
The 30-second spot, titled "Keep America Safe" and featuring footage from Rubio's presidential run, ties Democratic Senate contenders Alan Grayson and Patrick Murphy to presidential nominee Hillary Clinton.
"All three support the disastrous Iran deal, and would close Guantánamo," the ad's narrator says. "Standing in their way? Marco Rubio."
Sounding a bit like Republican presidential nominee Donald Trump, the narrator later intones that Rubio "took on Obama to block refugees from terrorist countries."
Beruff's campaign called the ad "fiction," saying Rubio tweaked his stances on refugees -- and missed important Senate work.
"Considering Marco Rubio's record of missing votes and ignoring his duties as Senator, it's no surprise his campaign and his establishment allies in Washington would have to make things up," spokesman Chris Hartline said in a statement. "But his record is clear: Marco Rubio just can't make up his mind on the issues that matter to Floridians and only fights the Obama Administration when it is politically convenient. Florida voters are fed up with this kind of failed leadership."
