“I worry a lot about non-professionals pursuing diplomacy in the name of” American diplomacy, said Rep. Francis Rooney, a Florida Republican and former US ambassador under George W.

It’s not as much about the substance of what is alleged — although members are holding their breath about if more comes to light — but it is about his style: his brashness, his unpredictability and his ability to show up on one cable news show after another without much warning.
