UPDATE 6:56 p.m.: David Weprin's campaign sent the following response to Turner's new ad.

"As we approach the tenth anniversary of 9/11, it's shameful that Bob Turner is trying to use the tragedy for his own political gain," Weprin said. "I knew people who lost their lives that day and Bob Turner dishonors their memory by politicizing the attacks on New York."

Republican Bob Turner’s campaign for Congress released its first ad on Thursday, sending it out in an e-mail blast.

The ad, titled “Send a Message,” knocks Democratic candidate David Weprin and President Barack Obama for their positions on the Islamic community center and mosque near the Ground Zero site.

Weprin is shown on video in the add, expressing his support of the right of the mosque to build.

The Islamic center was a campaign issue in 2010, when former Congressman Anthony Weiner maintained that it was not the government’s right to tell religious institutions where they could and could not build.

Turner disagreed last year, and it is clear that he still does.

In the ad, a narrator talks over images of the Twin Towers in flames on Sept. 11, 2001.

“It’s been ten short years. Everyone remembers,” the narrator says. “Some, though, want to commemorate the tragedy by building a mosque on Ground  Zero. President Obama thinks that's a good idea. And so does Congressional candidate David Weprin.”

According to the Turner campaign, the ad is scheduled to run on cable news stations in Brooklyn and Queens in the lead up to the Sept. 13 election.

Turner's campaign is likely to keep turning up the heat as the campaign progresses. A poll released this week showed Weprin with a six-point lead in the race.
