Proctor resigned in 1891 to take a Senate seat, at which point he was replaced by Stephen B. Elkins. Harrison's close friend and former law partner, William H. H. Miller, became Attorney General. Harrison's normal schedule provided for two full cabinet meetings per week, as well as separate weekly one-on-one meetings with each cabinet member. Tariffs accounted for 60 percent of federal revenue in 1889, and were a major source of political debate in the Gilded Age. Most Republicans, however, preferred to spend the budget surplus on internal improvements and eliminate some internal taxes. They saw their victory in the 1888 election as a mandate to raise tariff rates.Harrison took an active role in the tariff debate, hosting dinner parties in which he would cajole members of Congress for their support of a new tariff bill. Representative William McKinley and Senator Nelson W. Aldrich introduced the McKinley Tariff, which would raise the tariff and make some rates intentionally prohibitive so as to discourage imports.
