President Donald Trump's border czar, Tom Homan, has ordered an internal review of Immigration and Customs Enforcement's hiring and screening procedures following a fatal shooting involving an ICE officer in Maine. Homan said the review will examine whether the agency's vetting process failed to identify issues in the officer's background before he joined the federal immigration enforcement agency. The review follows the July 13 fatal shooting of Colombian national Johan Sebastián Durán Guerrero in Maine by ICE officer David Brouillette. Court records and family members have alleged Brouillette had a history of domestic violence and mental health concerns before joining the agency, allegations that have prompted questions about ICE's screening procedures.

The shooting has become the latest in a series of fatal encounters involving federal immigration officers during the Trump administration's expanded immigration enforcement campaign. ICE has faced growing criticism over several recent shootings, including another fatal incident in Texas, leading members of Congress from both parties to press the Department of Homeland Security for greater accountability and oversight. In response, ICE has introduced mandatory body-worn cameras during vehicle stops while reviewing officer training and operational policies.
