Fiscal conservatives are poised to leverage a recent bombshell report on widespread fraud within the Obamacare program as a tool to thwart a temporary extension of enhanced premium subsidies, which are set to expire at the end of the year. 

GOP members who do not wish to extend the temporarily added subsidies for Obamacare plans will likely point to a new report from the Government Accountability Office, published earlier this month, that found possibly tens of billions of dollars in fraud and mismanagement of Obamacare subsidies.
