WASHINGTON (AP) — More than two million people who got health insurance under the new health care law have discrepancies in the data they provided — and it could jeopardize coverage for some of them. That’s according to a government document provided to The Associated Press.

The number represents about one out of every four people who signed up. It creates a huge paperwork headache for the government, and could expose some consumers to demands for repayment if they got too generous a subsidy.
