On any given day, he may be interviewed on Fox Business Network at sunrise, and again as the market closes on CNBC. CNN noted, he is “well-schooled in the arts of both economics and politics and is one of the most influential figures operating behind the scenes in Congress.”

Mark is a frequent contributor to The Wall Street Journal, where he was the subject of The Weekend Interview and whose editorial board nicknamed him “Mr. Capital Gains.” Mark regularly contributes to Fortune and The Hill, Capitol Hill’s leading newspaper.
