In an open letter published on TIME, Ibtihaj Muhammad, the first Muslim woman to wear a hijab when representing the United States at the Olympic games, called out U.S. president Donald Trump on what she described as his "campaign of terror" against American ideals.

In her letter, she addresses the U.S. president, saying:

"The climate of fear and hatred fueled and perpetuated by your campaign is gaining momentum through your actions in office. Since your election, I have been 'profiled' at the airport, accused of looking 'suspicious' and, on the streets of New York, I have been told to 'go back to my country.'”

She goes on to highlight the important contributions that America's Muslims have made to healthcare, education and all aspects of life in the country.

She also urged Trump to "look at the math".

"We do not have a refugee terrorist problem. It simply doesn't exist. But, I do fear a not-so-subtle campaign of terror now being waged on our American ideals of justice and equality." 

"Overcoming obstacles was my challenge as an athlete. It is now my challenge as a citizen. I once represented you. Now you represent me. I urge you to do so with the humility, thoughtfulness and kindness befitting your sacred office."

Muhammad shot to fame after her participation in the 2016 Rio Olympics as a sabre fencer. She is now one of the most well known Muslim American athletes in the country.

The letter was widely shared on Twitter, with many voicing their support to Muhammad and others thanking her for speaking up.  

Mohammad's letter comes in the wake of Trump's now-frozen second travel ban, and on the same day as news of his government's plans to prohibit specific electronic devices inside planes arriving in the U.S. from at least eight Muslim majority countries surfaced.
