The major negative thing Andrew Jackson is remembered for is the forced relocation of many Native Americans, particularly in the southeastern portion of the United States. He also triggered an economic depression by refusing to renew the charter of the Second Bank of the United States and then instituting inflation-control policies that triggered a panic, but that was primarily blamed on his successor, Martin Van Buren.
I would disagree with the statement "United States vs. Nixon expanded the power of the presidency." In reality, it shrank the power of the president.
In this Supreme Court case, Richard Nixon refused to give up taped conversations he had from the Oval Office. Nixon claimed that this action was protected by the idea of "executive privilege." This meant that because he was president, he had the ability to keep these tapes from going to the courts. However the Supreme Court, in a unanimous vote, stated that the president must give up the tapes. This showed that no person was above the law, including the president. This shows that the presidents are responsible to the courts and do not have special protection in legal cases.
