One thing all this indicates is that the more than ten week long lame duck period is entirely too long. It’s only natural that anyone, domestic or foreign, who has current and ongoing business with the US executive branch will want to deal with those who will be making the decisions in the future.
I see nothing wrong with these contacts, or even discussions about what future policies might be desirable. The incoming administration can’t take action until they are sworn in, but talking and planning does not equal some serious misstep.
Shorten the lame duck period to one month or less.
