Some presidential appointees in the Trump administration have very close business ties to the agencies for which they work, and the Trump administration might be working around ethics violations, according to a report Saturday.

The New York Times, working in collaboration with ProPublica, reports that an analysis of lobbying documents and interviews with current and former ethics officials found that at least two appointments may have violated the Trump administration’s own ethics rules. However, figuring out if there were ethics violations is near impossible because the administration is secretly issuing waivers to the rules.
