A Muslim legislator of the United States has said that she was harassed with hateful and Islamophobic language in Washington.

Ilhan Omar, who wears the hijab, said the taunts and threats occurred after she left the White House and headed to her hotel.

“I got in a cab and became subjected to the most hateful, derogatory, Islamophobic, sexist taunts and threats I have ever experienced,” she wrote on her Facebook page.

"The cab driver called me ISIS and threatened to remove my hijab."

Following the incident, Omar rushed to leave the vehicle and said she planned to report the incident as soon as she returned to Minneapolis, since the driver knew where she was staying in Washington.

"I am still shaken by this incident and can't wrap my head around how bold beings are becoming in displaying their hate towards Muslims," she asserted.

Ilhan Omar is a Somali American politician from Minnesota. She is the Director of Policy and Initiatives of the Women Organizing Women Network. In 2016, she was elected a Democratic–Farmer–Labor Party legislator in the Minnesota House of Representatives.

Her victory was notable in a year that saw Republican Donald Trump disparage Muslim immigrants and refugees before going on to win the presidency.

According to latest reports by the FBI, hate crimes against Muslims in the U.S. have risen 67 percent in 2015.
