The Huffington Post’s S.V. Dale and Christina Wilkie have written an interesting story about the Trump administration’s problems with leaks. The most interesting part has little to do with the leaks and everything to do with President Trump’s foreign economic policy:

President Donald Trump was confused about the dollar: Was it a strong one that’s good for the economy? Or a weak one?

So he made a call ― except not to any of the business leaders Trump brought into his administration or even to an old friend from his days in real estate. Instead, he called his national security adviser, retired Lt. Gen. Mike Flynn, according to two sources familiar with Flynn’s accounts of the incident.

Flynn has a long record in counterintelligence but not in macroeconomics. And he told Trump he didn’t know, that it wasn’t his area of expertise, that, perhaps, Trump should ask an economist instead.

Trump was not thrilled with that response ― but that may have been a function of the time of day. Trump had placed the call at 3 a.m., according to one of Flynn’s retellings ― although neither the White House nor Flynn’s office responded to requests for confirmation about that detail.
