Final answer:
Andrew Jackson expanded presidential power through his extensive use of vetoes and unilateral actions like the Indian Removal Act of 1830 and restructuring federal bank deposits.
Step-by-step explanation:
One way Andrew Jackson notably expanded presidential power was through his assertive use of the presidential veto and his role in the Indian Removal Act of 1830. Jackson used the veto as a policy tool, issuing twelve vetoes more than all previous presidents combined, which set a new precedent for future presidential vetoes based on policy disagreements. His assertive actions, such as the removal of Indigenous Peoples and depositing federal funds in local banks rather than in the Bank of the United States, demonstrated an expansion of executive power beyond explicit congressional mandates, leading to significant political and social consequences.
