How did new deal policies franklin d. roosevelt increase the power of the presidency over the federal government?

The New Deal was established in response to the “Great Depression” in the United States during the 1930s. These are an array of federal programs, financial improvements, and adjustments. This was led by Franklin Roosevelt. Since the American people were mostly irked by the collapsing economy, when Roosevelt started his office, he responded with a sequence of new programs addressing the economic problems. During his first 100 days of doing so, the Congress have listened to him and passed the programs he asked. From being at the bottom in 1933 the economy soared high during his presidency.
