It was originally 11 potential Supreme Court nominees, then he added 10 more. Then he added people he had nominated, such as Amy Coney Barrett, to make the 25.
It’s reported that he added the first 10 just to get Gorsuch onto the list.
The he keeps adding names keeps the Democrats having to use scattershot and waste resources on people who aren’t going to be picked. (Hardiman?)
Thanks.
