 Weinberg befriended Franklin D. Roosevelt in 1932 while working as a member of the Democratic Party's National Campaign Finance Committee, and successfully raised more funds than any other member.Since many on Wall Street had opposed Roosevelt in the 1932 presidential election, Weinberg stood out as a prime candidate for the new president's liaison to Wall Street.Indeed, in 1933, Roosevelt assigned Weinberg the task of organizing a group of corporate executives- called the Business Advisory and Planning Council – to serve as a bridge between the government and the private sector during the economic upheaval of the New Deal.
