South Bend, Indiana Mayor Pete Buttigieg tweeted on Monday that he has raised more than $7 million in the first quarter of this year.

Buttigieg, who has yet to officially announce his 2020 presidential campaign for the Democratic nomination, added that although the figure is a preliminary analysis, it is “out-performing expectations at every turn.”

The South Bend mayor thanked his supporters and said he would send out a “complete analysis later.”

Although Buttigieg’s donations are expected to be significantly less than other Democratic candidates for president, it is still an impressive haul for a relatively unknown in national politics who has not yet declared his candidacy, according to The Hill.

The mayor announced last month that he had received money from 76,000 individual donors, which is beyond the threshold determined by the Democratic National Committee for a spot in the first debate of the 2020 cycle.

Buttigieg, who is a Navy veteran and the only openly gay candidate, was a surprising third in an Emerson poll released last week of the Iowa caucus.

In that survey, former Vice President Joe Biden led the Democratic field with 25 percent, followed by Vermont Sen. Bernie Sanders at 24 percent and then Buttigieg at 11 percent.
