(NEXSTAR) – Democratic Rep. Dean Phillips is now seeing the rainbow after walking through the rain, as his father would say, months after he failed to win a primary contest against President Joe Biden, jeopardizing relationships within his own party in the process.

The 55-year-old multimillionaire House member from Minnesota was the lone Democrat to challenge Biden for the presidency, a campaign that was fiercely criticized by colleagues. Speaking with Nexstar at the Democratic National Convention in Chicago Tuesday, Phillips had no regrets about his "principled mission."

Over a year before major figures in the Democratic party would call for Biden, 81, to step down following a disastrous debate against former President Trump, Phillips was trying to convince his own party and the public that Biden was too old to serve another term.
