The Obama administration has revoked the award it planned to give an Egyptian activist who fought against "virginity tests" on female protesters but whose Twitter account included anti-American and anti-Semitic comments.

Spokeswoman Victoria Nuland says the State Department won't honor Samira Ibrahim because of the tweets. Some of the tweets praised attacks on U.S. diplomatic installations and against Israeli civilians in Bulgaria.

The department named Ibrahim among recipients of a women's award to be presented Friday by Secretary of State John Kerry and first lady Michelle Obama. But officials said Thursday they needed time to study her Twitter account, which she says was hacked.

Ibrahim is defending herself on Twitter, saying she didn't attack any religion. But she refuses to apologize to what she calls the "Zionist lobby in America."
