John Kevin Delaney (born April 16, 1963) is an American politician, businessman, and former attorney who was the United States representative for Maryland's 6th congressional district from 2013 to 2019. He was a candidate in the 2020 Democratic presidential primaries. On July 28, 2017, Delaney became the first Democrat to announce his run for president in 2020. Delaney did not run for re-election to Congress in 2018, choosing to focus on his presidential campaign. In November 2018, fellow Democrat David Trone was elected to succeed Delaney in Congress, and subsequently endorsed him for President in 2020. Delaney suspended his campaign on January 31, 2020, citing low poll numbers and wanting to avoid pulling support from other candidates. He later endorsed Joe Biden for president.
