Embattled Hillary Clinton aide Huma Abedin came out of the shadows and joined Twitter last night — for the sole purpose of attacking Ben Carson.

Abedin posted at 6:20 p.m., “You can be a proud American, a proud Muslim, and proudly serve this great country. Pride versus prejudice.”

Her first tweet was a not-so-veiled shot at the popular Republican presidential candidate.

Appearing on Meet The Press, Carson was asked by host Chuck Todd if he believed that “Islam is consistent with the Constitution.”

Carson responded, “No, I don’t, I do not… I would not advocate that we put a Muslim in charge of this nation.”

When asked if a president’s faith should matter, he replied, “If it’s inconsistent with the values and principles of America, then of course it should matter,” according to NBC News.

Carson has since clarified his remarks in an appearance on Hannity.

“If someone has a Muslim background and they’re willing to reject those tenets and to accept the way of life that we have and clearly will swear to place our Constitution above their religion … I would then be quite willing to support them,” he said, according to CNN.

“I don’t care what religion or faith someone belongs to,” Carson said. “If they’re willing to subjugate that to the American way and to our Constitution, then I have no problem with that.”

He further expanded in a Facebook post:

I could never support a candidate for President of the United States that was Muslim and had not renounced the central tenant of Islam: Sharia Law.

I know that there are many peaceful Muslims who do not adhere to these beliefs. But until these tenants are fully renounced…I cannot advocate any Muslim candidate for President.

In 2012, National Review documented some of ways America’s foreign policy was influenced by Abedin:

…since Secretary Clinton’s tenure began, with Huma Abedin serving as a top adviser, the United States has aligned itself with the Muslim Brotherhood in myriad ways. To name just a few (the list is by no means exhaustive): Our government reversed the policy against formal contacts with the Brotherhood; funded Hamas; continued funding Egypt even after the Brotherhood won the elections; dropped an investigation of Brotherhood organizations in the U.S. that were previously identified as co-conspirators in the case of the Holy Land Foundation financing Hamas; hosted Brotherhood delegations in the United States; issued a visa to a member of the Islamic Group (a designated terrorist organization) and hosted him in Washington because he is part of the Brotherhood’s parliamentary coalition in Egypt; announced that Israel should go back to its indefensible 1967 borders; excluded Israel, the world’s leading target of terrorism, from a counterterrorism forum in which the State Department sought to “partner” with Islamist governments that do not regard attacks on Israel as terrorism; and pressured Egypt’s pro-American military government to surrender power to the anti-American Muslim Brotherhood parliament and president just elected by Egypt’s predominantly anti-American population.
