After a last-minute decision to not vote on the Sandy relief bill, followed by strong pushback from New York and New Jersey politicians, the House is scheduled to vote later this week on two separate pieces of legislation. Andrew Grossman of The Wall Street Journal and Molly Ball of The Atlantic discuss the politics and details of the bills -- plus the continuing fallout from the fiscal cliff negotiations.

The last-minute fiscal cliff deal reforms tax rates, deductions, payroll taxes, and several other laws that will effect more than 3/4 of Americans in one way or another. Richard Rubin of Bloomberg answers some basic questions about the changes.

Paul Barrett, assistant managing editor of Bloomberg Businessweek and author of, Glock:The Rise of America's Gun, kicks off this month's series on gun ownership, starting with how the Stockton school shooting of 1989 inspired legislation, and whether there are parallels between that moment and the discussions following the Newtown, CT shootings.
