Donald Trump's former ethics czar saw some "horrifying" violations before he was shut out by the administration.

Walter Shaub, who was appointed director of the United States Office of Government Ethics during the Obama administration and spent nine months in the same role under Trump, told The Daily Beast's "New Abnormal" podcast that ethical breaches were big and plentiful under the former president.

"The worst thing was President Trump's failure to divest his conflicting financial interests, which he then made worse by promoting those financial interests aggressively using the presidency," Shaub said.

Members of the administration also used "secret waivers" as "get-out-of-jail-free" cards, but no one could ever produce those cards for Shaub.

"The secret of the secret waivers was that there were no secret waivers," he said. "They were just letting people break the rules."
