Joe Biden campaigned for president two times prior to his successful 2020 presidential campaign. He pursued the 1988 Democratic presidential nomination but withdrew after it was revealed that parts of his campaign stump speech had been plagiarized from British Labour Party leader Neil Kinnock without appropriate attribution. His 2008 presidential campaign never gained momentum, and he withdrew from the race after placing fifth in the Iowa Democratic caucus in January of that year. After Barack Obama secured the Democratic presidential nomination, Biden emerged as a front-runner to be Obama's vice presidential running mate, and on August 23 Obama officially announced his selection of Biden as the Democratic Party's vice presidential nominee.
