The Raleigh News & Observer reports that lawmakers have written a letter to the state attorney general regarding Blue Cross and Blue Shield of North Carolina’s activities on healthcare reform.

State lawmakers and attorneys are scrutinizing Blue Cross and Blue Shield of North Carolina for its attempt to influence the national health care debate through direct mail and possibly illegal automated phone calls.

The state Attorney General’s office confirmed Tuesday it was investigating North Carolina’s largest health insurer for prerecorded calls that started late last month. Based on a preliminary review, some calls linked to the company appear to have violated the law, according to a letter from a state attorney.

The letter from the lawmakers to the attorney general is here.
