Currently I am reading a book called In the Garden of Beasts, about William Dodd, he first US Ambassador to Germany during the Nazi era, appointed in June 1933. About the appointment, the author, Erik Larson, writes:
... Dodd called the White House and informed Roosevelt’s secretary that he would accept the job. Two days later Roosevelt placed Dodd’s appointment before the Senate, which confirmed him that day, requiring neither Dodd’s presence nor the kind of interminable hearing that one day would become commonplace for key nominations.The book is quite good thus far, by the way. I read Larson's The Devil in the White City a few years ago, and enjoyed it as well.
