Miami Herald - A new, sweeping review of all committees Rubio has sat on since taking office in 2011 paints a bleak picture of participation in the day-to-day responsibilities of the job. 80 percent of Commerce hearings and 85 percent of those held by Small Business, records show.
He has missed 60 percent of Foreign Relations hearings since joining the Senate despite making his committee experience a centerpiece of his qualifications for president.
He attended 68 percent of Intelligence Committee meetings, though that's based on 19 hearings for which records are available. The bulk, 245, were classified so records are unattainable.
