House Majority Leader Eric Cantor said Monday that the Obama administration's efforts to smooth the troubled rollout of the new health care law "is of little comfort" to the employees who have had their work hours slashed because of the new law's employer mandate.

Cantor, R-Va., called on President Obama to allow Health and Human Services Secretary Kathleen Sebelius to testify before Congress Thursday at a hearing on problems related to implementation of the new law. Sebelius has so far refused to testify at the House Energy and Commerce Committee hearing.

Cantor's remarks followed Obama's Rose Garden speech in defense of the law, which has suffered glitches and been shown to have raised health care premiums and deductibles for many since its Oct. 1 start.

Obama on Monday announced that a new team of computer experts is being put together to fix problems with the barely functioning health care law's website.

House Republicans, meanwhile, are focusing on highlighting Obamacare's flaws after weeks spent trying to defund the law in the battle over government spending legislation.

"The Rose Garden isn't big enough to fit the millions of American families receiving letters in the mail that the health insurance they like is being cancelled or that their premiums and out-of-pocket expenses are going up yet again," Cantor said in a statement. "The fact that the president is bringing in outside experts to work on the Obamacare website is little comfort to the thousands of workers, including those at more than 100 school districts across the country, that have had their hours cut because of Obamacare mandates."
