President Donald Trump is reportedly questioning aides about whether Corey Lewandowski personally benefited from Homeland Security Secretary Kristi Noem's $220 million advertising budget. Lewandowski, who has been with Noem since at least April of last year, has been a key figure in the investigation. The two, who are both married, have been subject to rumors about their relationship for years. Noem, who will be replaced by current Oklahoma Republican Sen. Markwayne Mullin, will be special envoy to the Shield of the Americas initiative on security in the Western Hemisphere.
