"Well, when the president does it, that means it is not illegal.”

That, of course, is a famous line from Richard M. Nixon, uttered during his interview by British reporter David Frost in May 1977. The president is above the law.

Trump seems to agree. Click here for an article by Chris Cillizza at The New York Times entitled "This is the single most dangerous thing Donald Trump said in his New York Times interview."

Maggie Haberman at the NYT tweeted:

Trump on his businesses/conflict q's: "The law's totally on my side, the president can't have a conflict of interest."

Cillizza says:

Or he could have taken the idea from former New York City mayor Rudy Giuliani, a close Trump adviser, who said the following to CNN's Jake Tapper this month about conflicts of interest: "You realize that those laws don't apply to the president, right? So the president doesn't have to have a blind trust. For some reason, when the law was written, the president was exempt."

And later on:

In short: Just because something isn't illegal doesn't make it right. (I made a similar argument about Hillary Clinton's relentless pushback that she had broken no laws with her private email setup. That was proven to be accurate — and also besides the broader point of right and wrong.)

Hiding behind the "well, there's no law that says I can't do this" is not exactly presidential. And a belief that the president isn't bound to do everything he can to avoid the appearance of conflicts of interest suggests a dangerous slippery slope about what a president can and should do in office.
