House Republicans on Thursday asked government auditors for a detailed accounting of the money being used to implement President Obama’s healthcare law.

Republican leaders on the Ways and Means Committee asked the Government Accountability Office (GAO) to investigate how much money the Obama administration has spent implementing the law — and how much it expects to spend through 2014, when most of the major provisions take effect.

The lawmakers asked for detailed information about the Center for Consumer Information and Insurance Oversight (CCIIO), which is handling the bulk of the implementation effort. They asked GAO to determine the total amount of money CCIIO plans to spend by 2014, and for a breakdown of spending on salaries, advertising, polling, travel and conferences.
