Andrew Binns got down on one knee and proposed inside the Wells Fargo Center after a slideshow of his relationship with Liz Hart played.
It was a welcomed distraction to a Democratic Party in turmoil following the resignation of DNC chair Debbie Wasserman Schultz and rumors that Russia may have been involved in leaking privileged Democratic Party emails.
The astonished Hart said yes and shared a kiss with Binns after the ring was placed on her finger.
"I did not know it was coming. I was completely caught in surprise," she told Inside Edition.
He explained how the proposal came about without her knowing.
"I convinced her we were going up [to the stage] for a photo at the podium. We took the photo, then played the slideshow," he said.
She added: "When the music and lighting changed, I knew something was going on. Then, I saw all of our friends and family around. It was the best moment of my life."
The couple first met three years ago working with Vice President Joe Biden on a trip to India. Their first date was inside the Taj Mahal.
Both of the couple's families and friends were in attendance to witness the proposal.
