In an appearance on the ABC News Sunday morning show This Week, incoming White House Chief of Staff Reince Priebus warned the Director of the Office of Government Ethics to “be careful” about criticizing President-Elect Trump’s conflicts of interest.

On Wednesday Director Walter Shaub Jr. called Trump’s plan to separate himself from his business “wholly inadequate” and “doesn’t meet the standards” set by other presidents or even Trump’s own nominees.

Said Priebus: “The head of the government ethics ought to be careful, because that person is becoming extremely political. Apparently, may have made a — publicly supported Hillary Clinton as calling out the president with information on Twitter about our disentangle — disentangling of the business over a month ago. So I’m not so sure what this person at Government Ethics, what sort of standing he has anymore in giving these opinions. I think Jason Chaffetz was correct to call for an investigation into the Government Ethics Department in the government for the positions that they’ve taken in this campaign.”
