IRS CEO defiant as Washington asks who's running things

Inside and outside the IRS, people want to know who is really running the agency. IRS CEO Frank Bisignano says it's the least of his worries.

Named last October to the newly invented role of IRS chief executive officer, Bisignano is instead focusing on what he calls a transformative overhaul using artificial intelligence to reduce staff workloads and taxpayer call times following a year in which the agency lost 25 percent of its workforce and billions in federal funding. But agency staff, union leaders and lawmakers say the former Wall Street executive hasn't backed up his claims and has instead stifled contracting processes needed to make the changes while serving as an enforcer of White House mandates.
