Don Kettl: IRS is, not surprisingly, unpopular on Capitol Hill

The Internal Revenue Service has lost about 10 percent of its budget since 2010. The result of that -- according to the Treasury Inspector General for Tax Administration -- is that the IRS can't collect as much tax money as it should be collecting. Don Kettl is a professor at University of Maryland's School of Public Policy. He tells In Depth with Francis Rose that tax collectors have been unpopular for a long time.
