The White House warned Friday that Republicans' effort to repeal healthcare reform would harm the economy.

Stephanie Cutter, an assistant to the president for special projects, wrote that "repealing the law would likely slow down the growth of our economy," on a day when the government posted a tick-down in the unemployment rate, to 9.4 percent.

"The House Republican Health Care Plan to repeal the Affordable Care Act and take away all the new freedom and control it gives the American people over their health care and give it back to insurance companies will not only raise costs for individuals and businesses, but it will hurt our economy," Cutter wrote.

The blog is meant to engage Republicans' arguments on their own terms. GOP lawmakers have called the health bill "job-killing," and made that description so central to their argument against President Obama's healthcare plan that they named the repeal bill the "Repealing the Job-Killing Health Care Law Act."

House Speaker John Boehner's (R-Ohio) office wouldn't let the White House's claims go unanswered on Friday.

"If you have a job, need a job, or run a business of your own, you should know that repealing ObamaCare is a critical step toward fixing our economy," wrote Don Seymour, the Speaker's deputy communications director. "If the new health care law remains in place, workers and job creators alike will suffer."

Boehner's office pointed to reports from the business community concluding that jobs would be eliminated under Obama's legislation, and would run up the deficit.

The White House effort looks to cash in on the positive momentum gained by Friday morning's jobs announcement, and the decrease in unemployment.
