The nation’s largest Muslim civil rights and advocacy group once again blasted Republican presidential front-runner Donald Trump Monday night, this time for declaring that no more Muslims should be allowed into the country.

Trump released a statement Monday calling for “a total and complete shutdown of Muslims entering the United States until our country’s representatives can figure out what is going on.”

In response, the Council on American-Islamic Relations slammed the billionaire businessman’s comments as “bigoted,” “reckless,” and “simply un-American.” Nihad Awad, the group’s executive director, compared Trump’s ideas to the fascism of Nazi Germany and the most vicious, violent racism of American history.

“Donald Trump sounds more like a leader of a lynch mob than a great nation like ours,” he said during an evening press conference at the group’s office near Capitol Hill.

Oussama Jammal of the U.S. Council of Muslim Organizations echoed CAIR, calling Trump’s remarks “outrageous.”

Trump made his comments following the recent mass shooting in San Bernardino, Calif., which appears to be have been inspired by the Islamic State terrorist group.

Rival presidential candidates from both parties moved quickly to condemn Trump’s remarks.

Texas Sen. Ted Cruz distanced himself from Trump, but didn’t condemn his remarks.

Monday wasn’t the first time CAIR has spoken out against Trump. Last month, the group slammed him for rhetoric that “reeks of Islamophobia and fascism” after he told NBC News he “would certainly implement” a government database to register and track Muslims in the United States.
