Which post 9/11 conspiracy theory claimed that former President Obama was not born in the United States?

The assertion that former President Obama was not born in the United States and that he is a Muslim is rooted in the "birther" conspiracy theory that emerged prominently after the September 11 attacks. This theory questioned Obama's eligibility to serve as President by alleging that he was born in Kenya, despite him being born in Hawaii, which is a U.S. state. The claims were fueled by political opposition and were part of a broader narrative aimed at undermining Obama's legitimacy.

This conspiracy theory gained significant traction, especially among certain political groups, and was often intertwined with broader narratives that sought to portray Obama in a negative light, including unfounded claims about his faith. The combination of questioning his birthplace and emphasizing the idea that he practices Islam was aimed at stoking fear and suspicion among the public during a time of heightened sensitivity to national security issues post-9/11.

In contrast, the other options presented do not capture the essence of this specific conspiracy theory. While there are various conspiracy theories surrounding figures in politics, the focus on Obama’s birthplace and religious affiliation is uniquely tied to the birther movement.
