Secretary of State Mike Pompeo said Thursday morning that Hoda Muthana, a woman known as an 'ISIS bride' for her decision to leave the U.S. and marry a terrorist fighter in Syria, is herself a terrorist and should never be allowed back on American soil.

'There are now over 800 terrorists that are being held, foreign terrorist fighters that are being held, in Syria today. She's just one of them. She is a terrorist,' Pompeo said on the 'Today' show.

'She's not a U.S. citizen. She ought not return to this country,' he said.

Muthana attorney Hassan Shibly told DailyMail.com on Wednesday that his client is a citizen because she was born in the U.S. He claimed the Trump administration is trying to make her a 'test case' to support the president's position that awarding birthright citizenship requires a misreading of the U.S. Constitution.

'The Trump administration has been trying to limit birthright citizenship,' Shibly said, claiming the president will likely 'try to use' the case 'against a much broader group of Americans, mostly Latino Americans.'

Secretary of State Mike Pompeo said Thursday that so-called ISIS bride Hoda Muthana 'is a terrorist' and has no basis to demand safe return to the U.S.

An attorney for the Muthana family warned Wednesday evening that President Trump is trying to turn his client into a birthright citizenship 'test case' by falsely claiming she has no legal rights within the United States

President Trump said Wednesday that he made the decision to bar the Alabama woman who left home to join ISIS in Syria from returning to the United States

Pompeo declared Thursday that Muthana's place of birth has no bearing on her citizenship, agreeing that her father's status as a foreign diplomat from Yemen placed her in a different category.

'That's right,' he said, responding to that scenario.

'She may have been born here,' Pompeo said. 'She is not a U.S. citizen, nor is she entitled to U.S. citizenship.'

The secretary of state suggested that Muthana is in a Syrian refugee camp because the U.S. military has been effective in neutralizing the terrorist threat from the ISIS army.

'You have to remember the context. We've now taken down all but the last square inch of the caliphate in Syria and Iraq. Millions of people liberated by President Trump and our administration. The great work that our soldiers have done on the ground.'

Shibly, executive director of the Council on American-Islamic Relations' Florida chapter, told DailyMail.com that he will file a lawsuit Thursday morning against the U.S. government, demanding her safe repatriation.

Pompeo seemed to agree with the idea that Muthana was never an American citizen because her father was a Yemeni diplomat; the Muthana family says that diplomatic status ended a month before Hoda was born

Her family attorney said Trump is likely to 'try to use it against a much broader group of Americans, mostly Latino Americans' if he wins the citizenship dispute with Muthana

Proof? This is the letter which the ISIS bride's family says show that she is a natural-born U.S. citizen. They say the State Department is claiming that her father was a diplomat when she was born but this letter shows she was not. DailyMail.com has not verified the letter and the State Department declined to comment

Pompeo said Muthana, who left home to join the Islamic State group in Syria, is not a U.S. citizen and will not be allowed to return to the United States

President Trump said Wednesday afternoon that he personally made the decision to bar the young woman who fled the U.S. to join ISIS in Syria from returning to the United States.

'I have instructed Secretary of State Mike Pompeo, and he fully agrees, not to allow Hoda Muthana back into the Country!' he tweeted.

Muthana, who has an 18-month-old son, wants to submit herself to the justice system, her attorney has said, claiming she was born in Hackensack, New Jersey and raised in Hoover, Alabama.

Diplomats' children are not entitled to U.S. birthright citizenship in the U.S. Shibly says her father had left his diplomatic post by the time of her birth and produced a letter from the U.S. Mission to the U.N. as evidence.

He told DailyMail.com that the Trump administration is trying to 'strip citizenship' from Muthana and 'they cannot do that without [a] process.'

Responding to a State Department spokesperson's suggestion that Muthana could have received a U.S. passport as a non-citizen, he said, 'That's garbage, literally garbage.'

He said Muthana has a Social Security Number and has always been and still is a U.S. citizen.

'Hoda is actually trying to engage the legal system and turn herself in,' he said, but Trump wants to push the problem out of the United States' jurisdiction. 'I think that's insane.'

Pompeo did not say Wednesday afternoon how the State Department reached its determination Muthana is not a citizen, and a spokesperson for the State Department did not provide clarification in an email exchange.

'Ms. Hoda Muthana is not a U.S. citizen and will not be admitted into the United States,' Pompeo said. 'She does not have any legal basis, no valid U.S. passport, no right to a passport nor any visa to travel to the United States.'

President Trump later took credit for the decision. Spokespersons for the White House were also unavailable for comment.

Hassan Shibly, an attorney for her family, said the U.S. government is trying to claim she's not a citizen because her father was once a diplomat. He wasn't when she was born, though

Her birth certificate, a copy of which was shared on Twitter her family lawyer and was not independently verified by DailyMail.com, shows that she was born Oct. 28, 1994 in Hackensack, New Jersey

Muthana, who left America four years ago to join ISIS, has previously been issued two U.S. passports – one when she was a child and another in 2014.

Her birth certificate, a copy of which was shared on Twitter her family lawyer and was not independently verified by DailyMail.com, shows that she was born Oct. 28, 1994 in Hackensack, New Jersey.

A State Department spokesperson did not address Shibly's claims directly but told DailyMail.com over email that Muthana 'was not born a U.S. citizen and she has never been a U.S. citizen' even though she was born in the United States.

'Passport applicants must establish their identity, citizenship and entitlement to a U.S. passport,' the person said. 'However, there are many reasons that an individual previously issued a passport may subsequently be found ineligible for that passport.'

For instance: 'If it is determined that the bearer was not entitled to the issued passport, the passport may be revoked and/or a renewal application denied.

'Ms. Muthana’s citizenship has not been revoked because she was never a US citizen,' the person stressed.

In the United States birthright citizenship is automatically awarded to anyone who his born in the country, with several exceptions.

One of those exceptions involves the children of foreign diplomats. Under the Immigration and Nationality Act, children of diplomats who are born in the U.S. are exempt and are not considered U.S. citizens at birth.

Shibly claims that Muthana's father was discharged from his United Nations post one month before his daughter was born, which means the exemption is not valid in her case.

Shibly accused Trump of trying to strip her of citizenship and leaving her stateless.

Secretary of State Mike Pompeo said the 24-year-old does not have a U.S. passport and isn't a citizen

The attorney challenged the president's 'power to strip citizens of their citizenship' in a response tweet that referred to Trump as the 'Dictator in Chief' and encouraged him to allow her to return and stand trial.

The administration's position could be challenged in court.

Shibly did say whether he would sue in response to an inquiry from DailyMail.com, following his call out on Twitter of the American president.

He told Trump, however: 'Sorry Dictator in Chief but you don’t have the power to strip citizens of their citizenship.

Hoda's first husband was Australian extremist Suhan Abdul Rahman who was killed in battle in Syria

'Our nation is a nation of laws and we must hold everyone accountable to them. Hoda is asking to be accountable to our laws and legal system and you are essentially giving a free pass.'

Trump has taken aim at birthright citizenship in the past. He claimed last year that he could unilaterally end it, although the executive order he threatened never came to pass.

Sources told the New York Times that U.S. authorities might not have enough to charge her and this is a 'legal dodge' in an attempt to offload her.

The Times wrote that Muthana's father provided proof that he had left his diplomatic post when he applied for his daughter's passport when she was a child.

U.S. authorities granted Muthana a passport as a child and gave her one again when she applied for renewal in 2014. She used her second U.S. passport to fly from Birmingham, Alabama to Istanbul, which she fled to join ISIS, her lawyer said.

Trump's attempt to keep her from returning to the U.S. comes on the heels of a similar case in the U.K.

A British teen who joined ISIS in Syria also had her UK citizenship revoked on Wednesday. Shamima Begum, who traveled to Syria in 2015 and now wants to return to Britain after giving birth in a refugee camp in Syria last week, was denied entry.

Prior to Pompeo's statement that the U.S. was revoking her passport, Muthana said in an interview with ABC News earlier on Wednesday that she hoped the U.S. government would pay for her to undergo therapy if she was allowed to return.

'I'm a normal human being who has been manipulated,' she said. 'I hope America doesn't think I am a threat to them and I hope they accept me...I hope they excuse me because of how young and ignorant I was.'

Asked what she would expect as a reasonable form of punishment for joining ISIS, she said: 'Maybe therapy lessons, maybe a process that will ensure us that we'll never do this again.

'Jail time, I don't know if that has an effect on people. I need help mentally as well, I don't have the ideology any more but I am just traumatized by my experience.'

Prior to Pompeo's statement, Muthana said in an interview with ABC News earlier on Wednesday that she hoped the U.S. government would pay for her to undergo therapy if she was allowed to return

She added that she cries herself to sleep 'almost every night' at the thought of being put behind bars.

'I know that when I do get back I probably will be sentenced to jail for I don't know how much time.'

Looking at her son, she said: 'Thinking that my last few moments with him is stuck in a prison before another prison...'

The lawyer said Muthana is putting herself at risk by speaking out against ISIS from a refugee camp where she has lived since fleeing the group a few weeks ago. She had to dodge sniper fire and bombs to leave.

She has married ISIS fighters twice in the time that she was overseas, both of whom are deceased. She said in a handwritten letter that her lawyer released that she realizes now that she erred in judgement.

'During my years in Syria I would see and experience a way of life and the terrible effects of war which changed me,' she wrote.

After fleeing her home in suburban Birmingham, Alabama in late 2014 and resurfacing in Syria, Muthana used social media to advocate violence against the United States.

In the letter, Muthana wrote that she didn't understand the importance of freedoms provided by the United States at the time.

'To say that I regret my past words, any pain that I caused my family and any concerns I would cause my country would be hard for me to really express properly,' the letter said.

The woman's father is willing to welcome her, but she is not in contact with her mother, Shibly told the Associated Press.

In her ABC interview, Muthana gave a confusing explanation for why she initially fled her parents' home to join ISIS, saying that it was because she wanted a more 'Americanized life' and no longer wanted to live under her parents' strict rule.

'I had a good relationship with my family but I wanted a more Americanized life. I just wanted to go out, I wanted to have, like, friends, go to places. I didn't get any of that,' she said. 'The only way out for me was to become practicing... to become more religious.'

Before she fled, she was part of a network of young Muslims who used Twitter to soak up extremist ideas. She said they were brainwashed and interpreted what they were told by predatory ISIS members 'very wrong.'
