“I think that the Flynn issue obviously is something that shows that in many respects this administration is in disarray and they’ve got a lot of work to do,” said McCain, a known Trump critic, even as he praised Trump’s defence secretary. “The president, I think, makes statements [and] on other occasions contradicts himself. So we’ve learned to watch what the president does as opposed to what he says,” he said.
