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.

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.

[9] Scholarships from his father's labor union (IBEW Local 164) as well as the American Legion, VFW, and the Lions Club helped Delaney attend college; he earned a B.A.

[16] In 2000, Delaney co-founded CapitalSource, a commercial lender headquartered in Chevy Chase, Maryland; the company provided capital to roughly 5,000 small and mid-size businesses before his departure.

[21] After redistricting following the 2010 census, Delaney decided to run for the newly redrawn 6th district against 10-term Republican incumbent Roscoe Bartlett.

The redrawn district's share of Montgomery County ended just two blocks from Delaney's home in Potomac.

"[24] During the primary, Delaney was endorsed by former President Bill Clinton, U.S. Congresswoman Donna Edwards, Comptroller Peter Franchot, The Washington Post, and the Gazette.

[30] Delaney faced a closer-than-expected contest for reelection against Dan Bongino, the Republican candidate in 2012 for U.S. Senate from Maryland.

[2] Delaney favored universal health coverage and proposed a public plan that would cover all Americans under the age of 65 (while leaving Medicare for those over 65 untouched).

[40] He opposed Medicare-for-all, arguing that advocacy for the policy would help incumbent President Donald Trump get re-elected.

He cited his failure to gain traction in polls and wanting to avoid pulling support from other moderate candidates as reasons behind the suspension of his campaign.

[48] He has received the top score of 100 from the Human Rights Campaign for his support of equality-related legislation, with him stating "No one should be discriminated against because of who they are or who they love" in response to this recognition.

[51] Delaney and his wife April (née McClain) met at Georgetown University Law Center.

[57] He was also a member of the Board of Directors of several organizations: St. Patrick's Episcopal Day School (Chairman), Georgetown University, National Symphony Orchestra, and the International Center for Research on Women.
