Mitt Romney's presidential campaign has raised $5.5 million since the Supreme Court ruled that President Obama's healthcare law is constitutional.

Romney started raising funds immediately after the decision, and in a message to supporters Friday morning his campaign spokeswoman said he had raised $5.5 million from 55,000 donations. 

Obama's campaign blasted Romney's team for touting its fundraising success.

Obama outraised Romney after the decision, the president's reelection team claimed, but they did not share their fundraising numbers.

"It's perverse that Mitt Romney won't share details about what he'd do for the millions he'd leave uninsured or at the whims of insurance companies when he 'kills Obamacare dead,' but he'll share the hourly details of his fundraising after the Supreme Court ruling," campaign spokesman Ben LaBolt said in a statement. "We've outraised the Romney campaign in that time period but that's not the point -- our supporters are more committed than ever to ensuring that insurance companies can't drop coverage for people who get sick or discriminate against people with preexisting conditions by reelecting the President."

This morning, the Romney campaign had raised $4.3 million less than 24 hours since the court's ruling.

"As of this morning, we have raised $4.3 million with 43,000 donations online," spokeswoman Andrea Saul said early Friday.

"The Supreme Court may have found ObamaCare constitutional, but it remains just as disastrous for job creators as the day the law was passed. ObamaCare is a job killer — it raises taxes, cuts Medicare and puts government between patients and their doctors," Saul added.


Romney responded to the ruling by renewing his pledge to repeal the Affordable Care Act, known as "ObamaCare." 

He wrote in a fundraising email to supporters on Thursday: "Today, the Supreme Court upheld ObamaCare. But regardless of what the court said about the constitutionality of the law, ObamaCare is bad medicine, it is bad policy, and when I’m president, the bad news of ObamaCare will be over."

The Supreme Court's ruling was a clear win for President Obama, who counts the healthcare bill as a signature achievement of his first term. But Romney and other Republicans made clear they would not give up the fight to repeal what they call a government takeover of healthcare. Early signs indicate the ruling also stirred up voters who could be active in the November election.

Romney's campaign had raised $2.5 million by 1:33 p.m. Thursday.
