TUESDAY, April 1, 2014 (HealthDay News) -- An 11-hour surge of consumers signing up for health insurance under the federal Affordable Care Act pushed the number to 7.1 million participants as the first enrollment period came to a close Monday, the White House announced Tuesday.
"The Affordable Care Act is here to stay," President Barack Obama announced during a speech at the White House Rose Garden Tuesday afternoon.
Obama, who championed the controversial health reform law that some call Obamacare, added: "The bottom line is this: Under this law, the share of Americans with insurance is up, and the growth of health care costs is down. And that's good for our middle class, and that's good for our fiscal future."
The U.S. Centers for Medicare and Medicaid Services reported that Monday was a "record-breaking day of operations -- with more than 3 million visits to HealthCare.gov and more than 1 million calls to the call center as of 8 p.m."
CNN reported Tuesday that the last-minute surge of consumers included many young adults, whose enrollment is considered crucial because they tend to be healthy and their insurance premiums are intended to help cover the health care needs of older, sicker participants.
Quoting an anonymous government official, the network reported that "insurance companies were confident the percentage of young people was sufficient for the insurance marketplaces to function properly."
The law -- which the White House says is intended to reduce the number of Americans without health insurance, estimated last year to be 45 million -- remains highly unpopular with Republicans.
Michael Steel, a spokesman for House of Representatives Speaker John Boehner, R-Ohio, said the Affordable Care Act was hurting, not helping, Americans, the Associated Press reported.
"Every promise the president made has been broken: Health care costs are rising, not falling. Americans are losing the doctors and plans that they like -- especially seniors suffering under President Obama's Medicare cuts. Small businesses are afraid to hire new workers, hobbling our economic growth. That's why we must replace this fundamentally flawed law with patient-centered solutions that will actually lower health care costs and help create jobs," he said.
