White House knew millions could not keep their health insurance

President Obama repeatedly assured Americans that after the Affordable Care Act became law, people who liked their health insurance would be able to keep it. But millions of Americans are getting or are about to get cancellation letters for their health insurance under Obamacare, say experts, and the Obama administration has known that for at least three years. Four sources deeply involved in the Affordable Care Act tell NBC NEWS that 50 to 75 percent of the 14 million consumers who buy their insurance individually can expect to receive a "cancellation" letter or the equivalent over the next year because their existing policies don't meet the standards mandated by the new health care law.
