The liberal group Americans United for Change is targeting Florida media markets as part of a campaign to build support for the nuclear deal with Iran.
The group's $500,000 ad buy includes Miami and West Palm Beach markets, as well as Los Angeles, New York City, Baltimore, Boston, Providence and Washington, D.C.
In the ad, the group warns not to trust some of the critics who oppose the Iran deal because they were also members of President George W. Bush's administration.
"The same people that rushed us into war in Iraq want to sink the new agreement that would help stop war with Iran," the ad states with pictures of former vice president Dick Cheney and George W. Bush flashing on the screen.
The ad is scheduled to air over the next two weeks. Congress is expected to take up the Iran nuclear deal in September.
