Members of a Chicago-based Muslim civil rights organization and advocacy group called on local elected officials to stand up against the Trump administration’s detainment of students who have shown support of Palestinian causes, during a news conference.

So far this year, the Chicago Council on American Islamic Relations received about 400 complaints of discrimination against Muslim-Americans—the same number it received during all of 2016. 

The Council on American-Islamic Relations filed a federal lawsuit Monday over the constitutionality of President Donald Trump’s executive order, which they say targets Muslims.
