Large-scale ICE enforcement operations are typically kept secret to avoid tipping off targets. In 2018, Trump and other senior officials threatened the mayor of Oakland, California, with criminal prosecution for alerting city residents that immigration raids were in the works. ...
Publicizing a future law enforcement operation is unheard of at ICE. Trump administration officials blasted Oakland Mayor Libby Schaaf last year for warning immigrants about an impending raid, saying she endangered agents’ safety.
“The Oakland mayor’s decision to publicize her suspicions about ICE operations further increased that risk for my officers and alerted criminal aliens - making clear that this reckless decision was based on her political agenda with the very federal laws that ICE is sworn to uphold,” then-ICE deputy director Thomas Homan said at the time.
