More than 6 million Americans have signed up for health insurance through Obamacare, President Barack Obama announced Thursday.
That meets a goal set by the Congressional Budget Office, but it's still short of the original target of 7 million.
"It's people from all over the country," White House adviser Phil Schiliro said. "We do know it's a mix of people, and we know it's a lot of people."
But conservatives question the numbers, saying not all of them are actually paying premiums but have simply selected a plan.
Meanwhile, Obamacare ran into more problems this week when the president moved the individual mandate deadline from March 31 to April 15.
House Speaker John Boehner, R-Ohio, called the extension "a joke."
"Listen, this is part of a long-term pattern of this administration manipulating the laws for its own convenience," Boehner said.
But White House officials viewed the matter differently.
"I can't think of another law that has been subject to such a sustained barrage of attacks, most of them completely baseless, but that has an impact on public opinion," Schiliro said.
Still, the plan is losing favor with the public.
An Associated Press GfK survey, released before the president's announcement, found only 26 percent of Americans support the Affordable Care Act.
Obamacare is also losing support among young healthy millenials who are needed to pay for it. The latest report showed only 27 percent make up the total number of enrollees.
"When they (millenials) do the math for themselves and they look into what it's going to cost them and they realize that the rise in premiums and the rise in costs is just not affordable," Patrice Lee, manager of Generation Opportunity, explained.
We've also seen a lot of young people lose their health care coverage because of Obamacare," she said.
