With all the bragging from right wingers about Trump's choices for the Supreme Court, the irony of complaining about court stuffing is just dripping from every post.
Not seeing "irony"? Keeping the USSC at 9 justices is normal. Adding justices so the USSC is 11, 13 or even 15 members is what is termed "packing". FDR tried to get as many as 15 justices, but that plan was rejected by the House and Senate as interfering with the independence of the courts.
BRIA 10 4 a FDR Tries to "Pack" the Supreme Court - Constitutional Rights Foundation
"On February 5, 1937, President
Franklin Roosevelt announces a controversial plan to expand the
Supreme Court to as many as 15 judges, allegedly to make it more efficient. Critics immediately charged that Roosevelt was
trying to “
pack” the
court and thus neutralize
Supreme Court justices hostile to his New Deal."
