(CNN) - Republican U.S. Senate candidate Gabriel Gomez is calling on his Massachusetts opponent, Democratic Rep. Ed Markey, to take down a web video showing him on screen with Osama bin Laden.
"Career Politician Ed Markey has started his campaign with a textbook despicable political attack to attempt to connect me with Osama bin Laden in the minds of voters," Gomez said Saturday.
The former Navy SEAL called the video an "insult to my service and an insult to the intelligence of the people of Massachusetts," demanding his opponent take the video down immediately.
But Markey's campaign sees things differently, pointing to Gomez's past work for the special interest group called Special Operations OPSEC Education Fund, which accused President Barack Obama of "politically capitalizing on U.S. national security operations and secrets" after the bin Laden raid.
"Gabriel Gomez is now attacking Ed Markey for a web video containing video footage of Gomez's own advertisement that accused President Obama of politicizing the death of Osama bin Laden, and risking Americans' lives," Markey's campaign said responding to Gomez's demand for the ad to be taken down.
In the web video, titled "Meet Gabriel Gomez: Just Another Republican" shows a clip from MSNBC where Gomez and an image of the September 11, 2001, terrorist mastermind are displayed side-by-side. In the clip, Gomez is seen defending the group.
In denouncing the video, Gomez's campaign sent out a release Saturday with Medal of Honor Recipient Thomas Hudner calling Markey's ad "dishonorable" but Markey's campaign suggests their opponent is being hypocritical.
The controversy comes just days after each candidate won his party’s nomination to contest for the open Senate seat left vacant when John Kerry became secretary of state.
The two will compete in the special election on June 25. William "Mo" Cowan is currently serving as interim senator, appointed by Democratic Gov. Deval Patrick.
The race has been overshadowed by the Boston Marathon bombing that left three people dead and more than 260 others injured.
The candidates suspended campaigning for nearly a week following the attack. Though the campaigns are up and running again, media attention continues to be saturated with the bombing investigation.
