For “Michele Bachmann and some people of the Tea Party movement — the fact that we are Muslim means we are disloyal to our country and have hidden agendas,” Ms. Sarsour said.

She denies having any contact with Hamas or other radical Muslim groups. Otherwise she never would have received a “Champion of Change” award from President Barack Obama some months ago, she said.

Ms. Sarsour, 32, sees the attacks against her and Ms. Abedin as a new stage of Islamophobia.

“Michele Bachmann, Peter King and their colleagues are trying to further marginalize Muslim Americans from civic engagement and political life,” she said. “I have news for them: It’s not working.”

The women interviewed for this column said it was time for those who are attacking them to look more closely at the reality on the ground in some Arab countries. Though rightly criticized for dealing harshly with protests, those governments may have more tolerance than the United States or European countries for members of religious minorities, they say.

“It is always easy to point with your fingers on Arab countries and remark that they aren’t democracies,” said another of the four women with government jobs. “But then you see how they got advisers and ambassadors of other religious backgrounds than the majority.”

The women mentioned Morocco, whose king has Jewish advisers, and Bahrain, which is still the site of conflict between the mainly Shiite-led opposition and the ruling family and government, but has a Jewish female ambassador in Washington, a Christian one in London and several Shiite ambassadors and ministers.

Alice Thomas Samaan, the Bahraini ambassador to Britain, said by telephone that she was saddened by the attacks on Muslim women like Huma Abedin, Linda Sarsour and Samar Ali. “I had hoped that there is a difference in the U.S. about Islam, and loyalty and disloyalty has nothing to do with the religion,” Ms. Samaan said.
