House Republicans, who are continuing their efforts to chip away at President Obama's healthcare law, have now set their sights on a powerful group that strongly supported the legislation: the AARP seniors lobby. Two GOP members of the House Ways and Means Committee released a report Wednesday alleging that the nation's largest seniors group stands to gain financially from the Affordable Care Act, because the law could result in greater demand for supplemental Medicare policies that carry the AARP stamp of approval. In addition, the Ways and Means health and oversight subcommittees have scheduled a joint hearing Friday to grill AARP officials about the organization's financial ventures. "This hearing is about getting to the bottom of how AARP's financial interests affect their self-stated mission of enhancing seniors' quality of life," said Rep. Wally Herger (R-CA), who chairs the panel's health subcommittee. "It is important to better understand how AARP's insurance business overlaps with its advocacy efforts and whether such overlap is appropriate."
