Well, the reason they were discussing it is b/c they were interviewing the Chairman of the Government Accountability Office who is the one who proposed it, from what I understand.
However, IHB also is discussing it: President Obama created the bipartisan commission in February to provide options on overhauling the tax system and reducing the national deficit. According to a November report, one option excludes citizens from deducting interest payments on second residences, home equity loans or mortgages over $500,000.
