Roosevelt announced he wanted to add more judges to the Supreme Court to make it more efficient. He stated there were not enough judges to make informed decisions.
Roosevelt's opposition claimed he was trying to "pack" the court with liberals to protect his New Deal programs. Though this may have been true, it was not the message Roosevelt provided to the public. The public message was that the Court had become inefficient and unable to rule on judgments effectively so new judges were needed as well as replacing those that could retire.
