Federal Agents Were Told FBI Will No Longer Investigate ICE Confrontations

WASHINGTON — Federal agents around the country were told in recent days that the FBI would no longer investigate confrontations with immigration agents — cases that sometimes yield evidence that could be used to prosecute Department of Homeland Security agents implicated in violent encounters, according to people briefed on the decision. If enacted, such a change would sharply limit law enforcement scrutiny of immigration agents, as the Trump administration draws mounting criticism over killings at the hands of federal officers.
