President Donald Trump's administration has directed U.S. prosecutors to criminally probe state and local officials who resist immigration enforcement efforts, intensifying a sweeping crackdown that Trump launched the day he took office.

Illinois is already fighting back against one of President Trump’s actions to crack down on immigration. Illinois Attorney General Kwame Raoul filed a lawsuit Tuesday challenging Trump’s executive order ending birthright citizenship for the children of undocumented immigrants.

Activists monitoring for immigration arrests said they had seen no activity, but the threat of deportations continues and the local community should remain alert.
