Sunday turned out to be a great day for Mayor Pete Buttigieg. Shortly after his speech officially declaring his candidacy, the mayor’s communication director said he had raised a whopping $1 million.

“Some news: since delivering his announcement speech, our grassroots supporters have invested more than $1m in @PeteButtigieg’s campaign,” Lis Smith wrote on Twitter.

Earlier today, in a presidential declaration that drew a comparison to President Barack Obama , Buttigieg entered the race.

“My name is Pete Buttigieg. They call me Mayor Pete,” Buttigieg told the crowd. “I am a proud son of South Bend, Indiana. And I am running for President of the United States.”

He added: “I recognize the audacity of doing this as a Midwestern millennial mayor. More than a little bold—at age 37—to seek the highest office in the land. … But we live in a moment that compels us each to act.”
