President Donald Trump has told advisers he has decided to remove Homeland Security Secretary Kirstjen Nielsen, the Washington Post reports, and her departure from the administration is likely to occur in the coming weeks, if not sooner.

Trump, writes the Post, has grumbled for months about what he views as Nielsen’s lackluster performance on immigration enforcement and is believed to be looking for a replacement who will implement his policy ideas with more alacrity. The president canceled a planned trip with Nielsen this week to visit U.S. troops at the border in Texas and told aides over the weekend that he wants her out as soon as possible, the Post reported, citing officials.

DOJ expected to issue Whitaker opinion: CNN reports the Justice Department is expected to issue an opinion from the Office of Legal Counsel on Tuesday that will defend Matthew Whitaker’s appointment as acting attorney general under federal law. Almost immediately after Whitaker was appointed last week, various high-profile lawyers, professors and former DOJ officials weighed in on the legality of the move, and more formal legal challenges are widely expected.
