Curiously ... "The names of the nomineesand other information about the nominations cannot be revealed until 50 years later."
Secret? WTF?
You did not know that? The people who nominate them can always make it public. So some random congressperson nominates trump, and then she calls up a right wing news source and says she did it. It means nothing.
There are literally tens of thousands of people who can nominate someone for a Noble Peace Prize.
