Sister-Diana-MomekaA group of religious minorities set to testify about their oppression at the hands of the self-proclaimed Islamic State will be short one member after the Obama administration blocked her from entering the United States.

You should be shocked, but you won’t be.

She just happens to be the only Christian.

And she’s hardly a threat.

She’s a nun.

“Sister Diana Momeka was the only Christian in the delegation and the only member blocked from the trip, leading some of her American supporters to question why she was singled out,” The Washington Times reports.

“The sister was told Tuesday by the U.S. consulate in Erbil that her application for a non-immigrant visa had been rejected on the grounds that she was ‘not able to demonstrate that [her] activities in the United States would be consistent with the classification of the visa,’ according to her denial letter.”

“According to sources close to the situation, the Dominican sister’s paperwork wasn’t even reviewed due to the fact that she is currently considered an internally displaced person (IDP), forced to leave her home because of the Islamic State,” the Times reports.

“Sister Diana was told that as long as she was an IDP, she would not be able to receive a U.S. visa. But her supporters were able to point to several recent delegations of persecuted minorities, including IDPs, who were all granted visas to travel to the U.S.”

Sister Diana had a letter of recommendation from Rep. Anna Eshoo, a California Democrat.

Eshoo’s father is a Chaldean Catholic whose father fled religious persecution in Iran.

Sister Diana is a former U.S. resident, having fled to the United States in 2012 seeking refuge from violence in Iraq.

She also earned a doctoral degree in ministry from the Catholic Theological Union in Chicago in 2012, and even gave the commencement address.

The State Department refuses to comment on their denial.

Human rights activists find a cruel irony in the Obama administration silencing someone trying to testify on human rights abuses.

“Sister Diana, who we had hoped would come to Washington to speak about the worsening plight of Iraq’s displaced Christians and other beleaguered religious minorities, was apparently prevented from doing so precisely because she is herself a displaced person,” said Elyse Anderson, 21st Century Wilberforce Initiative’s senior adviser and director of special projects.

Obama has repeatedly ignored violence against Christians in Africa and the Middle East. His efforts to launch the “Arab Spring” led to attacks and oppression of Egyptian Christians by the Muslim Brotherhood. Obama has worked to undermine Egypt’s new president, Abdul Fattah el-Sisi, who has offered protection and support for the nation’s Christian minority.

It wasn’t until two months after ISIS launched its assault on Iraq that Obama acknowledged their oppression of religious minorities, giving only a passing mention of their brutal torture, rape and murder of Christians.

The White House has not commented on the bizarre decision to ban Sister Diana from entering the United States.
