Final answer:
The statement is false, as Grant's Vice Presidents were Schuyler Colfax and Henry Wilson, not William Tweed. Tweed was involved in New York City's Tweed Ring scandal.
Step-by-step explanation:
The statement "William Tweed was Grant's vice president" is false. Ulysses S. Grant, who served as the 18th President of the United States, did not have William Tweed as his Vice President. Instead, Grant's Vice Presidents were Schuyler Colfax during his first term (1869-1873) and Henry Wilson during his second term (1873-1875). William Tweed was a politician in New York known for being involved in the Tweed Ring, a group that defrauded New York City out of millions of dollars. In fact, Samuel Tilden, who was instrumental in breaking up the Tweed Ring, ran for President as a Democrat against the Republican candidate Rutherford B. Hayes after Grant's presidency.
