(CNN) - The campaigns of President Barack Obama and Republican challenger Mitt Romney, as well as at least one of the major super PACs supporting their candidacy, will not run television commercials on September 11 this year, the campaigns and organization confirmed Thursday evening.
Priorities USA Action, the primary pro-Obama super PAC, also said Thursday they will not run spots on the day. A spokeswoman for the pro-Romney super PAC Restore Our Future did not immediately respond regarding Restore's advertising plans.

In 2008, candidates Obama and Sen. John McCain paused their campaigns on September 11 and jointly visited Ground Zero in New York City in commemoration of the 2001 attacks.
While in New York earlier this year, Obama visited the site of One World Trade Center and signed a beam which was recently installed in the tower.
In April, Romney and Rudy Giuliani, who was mayor of New York City at the time of the attacks, marked the one-year anniversary of the 2011 raid which killed Osama bin Laden by delivering pizzas to New York Engine Company 24, which played a central role in the 9/11 response.
The campaign ad suspension was first reported by The New York Times.
