Explanation:

Tweed was elected to the United States House of Representatives in 1852 and the New York County Board of Supervisors in 1858, the year he became the head of the Tammany Hall political machine. He was also elected to the New York State Senate in 1867, but Tweed's greatest influence came from being an appointed member of a number of boards and commissions, his control over political patronage in New York City through Tammany, and his ability to ensure the loyalty of voters through jobs he could create and dispense on city-related projects.

Tweed was convicted for stealing an amount estimated by an aldermen's committee in 1877 at between $25 million and $45 million from New York City taxpayers through political corruption, although later estimates ranged as high as $200 million.[4] Unable to make bail, he escaped from jail once, but was returned to custody. He died in the Ludlow Street Jail.
