SPRINGFIELD – Illinois Attorney General Kwame Raoul fileda federal lawsuitThursday against U.S. Attorney General William Barr over a Trump administration policy requiring state and local law enforcement agencies to cooperate in federal immigration enforcement. It is the second such lawsuit Raoul’s office has filed challenging the Trump administration’s requirement that in order to receive federal law enforcement grants, state and local governments must show that they cooperate with the Department of Homeland Security in enforcing federal immigration laws. “As Attorney General Barr is likely aware, it is unconstitutional to place immigration-related conditions on funding for Illinois law enforcement,” Raoul said in a news release.
