The Justice Department wants federal prosecutors across the country to investigate state or local officials who obstruct immigration enforcement under President Trump's new administration, according to a new memo obtained by Fox News. 

"The Justice Department must, and will, work to eradicate these threats," Acting Deputy Attorney General Emil Bove, Trump's former defense attorney, wrote in the memo. "Indeed, it is the responsibility of the Justice Department to defend the Constitution and, accordingly, to lawfully execute the policies that the American people elected President Trump to implement."
