President Barack Obama and Mitt Romney agreed to a truce on the airwaves on Tuesday to mark the 11th anniversary of the 9/11 terrorist attacks.

But the Obama campaign broke that truce, posting a commercial online Tuesday that accused Romney of being “dangerous” for women’s health.

“Mitt Romney’s position on women’s health — it’s dangerous,” a woman says in the ad. “We can’t afford to let him take away our choices, to take away basic health care.”

Earlier in the day, a pre-recorded segment aired in which Obama called into a radio show in Florida hosted by the “Pimp with the Limp” and attacked Romney.

The Obama campaign claims the attack ad against Romney has been airing since September 4th and was not aired on Tuesday.
