Answer:
He wanted to appoint justices that would likely support the New Deal.
Step-by-step explanation:
Franklin D. Roosevelt attempted to "pack" the Supreme Court because "He wanted to appoint justices that would likely support the New Deal."
Roosevelt became the United States president following the occurrence of the Great Depression. To solve the problems of the Great Depression, Roosevelt sought to create New Deal measures to counter the effect of the Great Depression.
However, at the initial stage, the Supreme Court nullified numerous New Deal programs proposed by Roosevelt. Hence, to solve the problem, he appointed more justices that would likely support the New Deal.
