Former Maryland Representative John Delaney was the first major Democrat to declare a presidential bid.
Delaney, who was a US representative from 2013 to 2019, announced his decision to run on July 28, 2017.
In a Washington Post op-ed announcing his candidacy, Delaney said "The current administration is making us less prosperous and less secure. I’m running because I have an original approach to governing and an economic policy that can put us on a different course."
