Hmmm, an interesting question indeed.

   "The Washington Examiner reported on Monday that Mark Everson, Commissioner of Internal Revenue from 2003 to 2007, during the Bush administration, visited the White House exactly once while in office. Indeed he felt like he’d “moved to Siberia” so out of the ordinary political loop was he. But Douglas Shulman, Commissioner from 2008 to 2012, during the Obama administration, visited the White House 118 times just in 2010 and 2011. His successor, Steven Miller, also visited “numerous” times.

The Commissioner of Internal Revenue is a managerial position, not a policy-making one, although his input on the practical realities of tax collection and how the IRS is structured might well be very useful if the President was planning a big push on tax reform. But no such push has been forthcoming. Obama’s sole interest in the tax code has been to raise rates on high earners. So what was the commissioner doing going to the White House more than once a week on average?"
