However, two senior administration officials told BuzzFeed News that those within the administration believe acting Department of Homeland Security Secretary Kevin McAleenan, or his staff, leaked operational details and that is what ultimately put the ICE operation in jeopardy.

“Leaking the locations and details to stop the operation from happening not only harmed operational integrity, but it put the safety and well-being of his own officers in jeopardy,” said one senior administration official. “The ICE mission is enforcing the nation’s laws and ensuring those who are unlawfully present in the country are removed if ordered by a judge; this will leave an un-erasable mark on his tenure.”
