The news follows record high fundraising reported by the Democratic Congressional Campaign Committee (DCCC). That group pulled in $2.3 million between Thursday, the day the court handed down its ruling, and Saturday.
The healthcare decision was a fundraising boost for Republicans as well, with Mitt Romney's campaign reporting it raised $5.5 million from 55,000 individual donations within 24 hours after the ruling.
The Obama campaign claimed they outraised Romney's numbers, but did not provide numbers.
