New York City ? Vowing not to be “Swift boated,” Sen. Barack Obama, D-Ill., aggressively pushed back Wednesday against “ludicrous” rumors reported on Fox News that he attended a radical Islamic school.

Taking on Fox hosts Steve Doocy and John Gibson by name, Obama’s campaign blasted the “malicious, irresponsible charges” they aired.

The conservative Insight magazine reported last weekend that Obama attended a radical madrassa in Indonesia as a boy.

The Illinois Democrat, who is Christian, lived in Jakarta for a few years as a boy. Reporters for CNN and The Associated Press went to his school and found it a secular institution attended by students of all faiths.
