Hillary Clinton confidante Huma Abedin has finally joined Twitter - and she used her first tweet to slam one of her bosses' GOP rivals, Ben Carson, over his comments about Muslims.

'You can be a proud American, a proud Muslim, and proudly serve this great country. Pride versus prejudice,' she said. Abedin is a Muslim, although she is not known to have spoken of her religion in such a high-profile fashion before.

Abedin's tweet was a response to Carson's admission on Meet the Press that he wouldn't be comfortable with a Muslim president.

Hillary Clinton confidante Huma Abedin, seen here at a gala on Saturday night, has finally joined Twitter - and she used her first tweet to slam one of her bosses' GOP rivals, Ben Carson, over his comments about Muslims

Abedin's tweet was a response to Carson's admission on Meet the Press that he wouldn't be comfortable with a Muslim president

'I would not advocate that we put a Muslim in charge of this nation,' Carson said in an interview that aired on Sunday. He's seen here speaking at a conservative conference on Friday night in South Carolina

'I would not advocate that we put a Muslim in charge of this nation,' he said.

Carson argued on the Sunday morning show that Islam is 'inconsistent' with the Constitution.

He further explained to The Hill in an interview that evening that his concerns were tied to a set of rules that's enforced in Islamic countries known as Sharia law.

'I do not believe Sharia is consistent with the Constitution of this country,' he said. 'Muslims feel that their religion is very much a part of your public life and what you do as a public official, and that’s inconsistent with our principles and our Constitution.'

GOP MUSLIM BROTHERHOOD CLAIM Five Republican members of Congress, including the now retired conservative lawmaker Michele Bachmann of Minnesota, claimed in 2012 claimed that Hillary Clinton aide Huma Abedin's family had ties to the Muslim Brotherhood. They demanded the State Department investigate the allegation, earning push back from the Republican Party's 2008 nominee for president and U.S. Senator John McCain. McCain said they were 'unwarranted and unfounded attack on an honorable woman, a dedicated American, and a loyal public servant The State Department's spokesman at the time, Philippe Reines, another aide close to Clinton, said the charges were 'nothing but vicious and disgusting lies,' according to Politico.

Abedin is married to the disgraced congressman Anthony Weiner. She was born in Kalamazoo to an Indian-American father and Pakistani-American mother, both of them Muslim, raised mostly in Saudi Arabia and is fluent in Arabic and Urdu.

It is the language of Pakistan and was also traditionally the language of many Muslims in what is now India.

Carson's taken heavy criticism from across the political spectrum since his Meet the Press interview aired Sunday.

An influential Muslim-American group - Council on American-Islamic Relations - the White House, Democratic presidential candidate Bernie Sanders and several of Carson's GOP competitors have condemned the remarks.

'@RealBenCarson needs to apologize to American Muslims. He is a good doctor, but clearly not prepared to lead a great nation,' Lindsay Graham said Sunday on Twitter.

Jeb Bush said Carson's comments were 'not productive,' according to Fox News.

Abedin's boss, Hillary Clinton, said Monday morning on the platform, 'Can a Muslim be President of the United States of America? In a word: Yes. Now let's move on. -H'

She posted her position as a caption on a picture of the section of the Constitution stating that there can be 'no religious test' for public office.

Carson's sticking by his statements, though, and said last night on Fox News that he'd also be opposed to the U.S. becoming a theocracy.

'If you’re a Christian and you’re running for president and you want to make this into a theocracy, I’m not going to support you,' Carson told Fox's Sean Hannity. 'I’m not going to advocate you being the president.'

On Facebook, Carson fired back at his GOP rivals distancing themselves from his remarks, saying, 'Those Republicans that take issue with my position are amazing.'

'Under Islamic Law, homosexuals – men and women alike – must be killed. Women must be subservient. And people following other religions must be killed. 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.'

His campaign manager Barry Bennett told the Associated Press yesterday that Carson's comments had boosted, not detracted, from his fundraising efforts and social media following.

'While the left wing is huffing and puffing over it, Republican primary voters are with us at least 80-20,' he said.

Bennett said, 'People in Iowa particularly, are like: "Yeah! We’re not going to vote for a Muslim either." '
