Americans nationwide gathered on Saturday as most major news outlets announced Joe Biden and Kamala Harris as the winners in this year’s presidential race. It followed more than four days of ballot counting in several swing states with legal challenges from the Trump campaign expected to come.

Decision Desk HQ, the Bangor Daily News’ election partner, projected Biden and Harris the victors on Friday.

Here’s how supporters from both sides reacted to Biden’s victory on Saturday — from Portland, Maine to Phoenix, Arizona.
