WASHINGTON (AP) — The White House is asking insurance companies to explain to Americans the cancellation letters they're receiving in the mail.

President Barack Obama's chief of staff, Denis McDonough, met Tuesday with CEOs from some of the largest health insurers. The White House says McDonough updated the CEOs on fixes to healthcare.gov and problems with enrollment data sent electronically to insurers. McDonough also solicited input on whether the system is getting better.

The White House says McDonough urged insurance companies to "ramp up communication and education efforts" to those who have lost their insurance.

Millions have received cancellation notices, sparking outrage because Obama repeatedly promised that those who liked their health care could keep it. The White House says many of those losing coverage have better, cheaper options through the new exchanges.
