Spokeswoman for the US Department of Homeland Security (DHS) Tricia McLaughlin - one of the most prominent figures in the White House crackdown on immigration - plans to leave her post this week.
McClaughlin has vigorously promoted and defended President Donald Trump's deportation push across social media and in press interviews and podcasts.
She had planned to leave in December, but chose to stay on after two US citizens died in shootings involving immigration officers in Minnesota last month, sources told CBS News, the BBC's US partner.
DHS Secretary Kristi Noem confirmed McLaughlin's departure, saying she "has served with exceptional dedication, tenacity, and professionalism".
"She has played an instrumental role in advancing our mission to secure the homeland and keep Americans safe," said Noem.
