House Speaker John Boehner, speaking in advance of the president's announcement, insisted it was time to "scrap this law once and for all."
"You can't fix this government-run health care plan called Obamacare . ... It's just not fix-able."
While the White House deals with the cancellation issue, the administration is also promising improvements in a federal website so balky that enrollments totaled fewer than 27,000 in October in 36 states combined. The administration had said in advance the enrollment numbers would fall far short of initial expectations. After weeks of highly publicized technical woes, they did.
Adding in enrollment of more than 79,000 in the 14 states with their own websites, the nationwide number of 106,000 October sign-ups was barely one-fifth of what officials had projected — and a small fraction of the millions who have received private coverage cancellations as a result of the federal law.
The administration said an additional 1 million people have been found eligible to buy coverage in the markets, with about one-third qualifying for tax credits to reduce their premiums. Another 396,000 have been found eligible for Medicaid, which covers low-income people.
Administration officials and senior congressional Democrats expressed confidence in the program's future. "We expect enrollment will grow substantially throughout the next five months," said Sebelius, who is in charge of the program.
"Even with the issues we've had, the marketplace is working and people are enrolling," she added.
Despite the expressions, the White House worked to reassure anxious Democrats who are worried about the controversial program, which they voted into existence three years ago over Republican opposition as strong now as it was then.
Senate Democrats arranged a closed-door meeting for midday Thursday in the Capitol with White House officials, who held a similar session Wednesday with the House rank and file. Ahead of that meeting, Obama planned to speak from the White House about new efforts to help Americans receiving insurance cancellation notices.
