In fact, some might consider nominating Trump for a Peace Prize kind of embarrassing, which is probably why the US politician who nominated him remains anonymous.Each year, thousands of members of academies, university professors, scientists, previous Nobel Laureates and members of parliamentary assemblies and others, are asked to submit candidates for the Nobel Prizes for the coming year. These nominators are chosen in such a way that as many countries and universities as possible are represented over time.
