Obama addressed the United Auto Workers Union in Dubuque, Iowa Tuesday.
(CNN) - Sen. Barack Obama Tuesday dismissed an e-mail attack being circulated about him that questions his patriotism, and he vowed to vigorously defend himself from this assault as well as questions about his religious beliefs.
"I don’t mind them arguing with me about policy, but don’t let them question my patriotism," said Obama, responding to a question about the email following a speech before the United Auto Workers in Dubuque, Iowa. “And listen, I am not going to be swift boated at this race. If somebody comes at me I am going to come right back at them hard."
The e-mail purports to show Obama not placing his hand over his heart during a recitation of the Pledge of Allegiance at a campaign event.
"We were not saying the Pledge of Allegiance,” Obama said. “We were singing the Star Spangled Banner."
Obama also took time to respond to a rumor that claims he was educated in a madrassa, and raised as a Muslim.
"If I were a Muslim I would let you know," he said. "But I am a member of Trinity United Church of Christ on 95th street on the South side of Chicago. We got the best choir in town and if you all want to come and worship with us you are more than welcome."
When the madrassa rumor first surfaced in January, CNN sent a correspondent to Jakarta, Indonesia, and determined it was false.
