While Mitt Romney refuses to release his tax returns to the American people so they can have the information necessary to evaluate him as a presidential candidate, nonetheless, he did demand years of tax returns from the persons he considered for the Republican vice presidential nomination. From Buzzfeed:
Mitt Romney's presidential campaign requested "several" years of tax returns from potential vice presidential picks, senior adviser Beth Myers, who ran the search, told reporters Saturday. Myers said vetting documents were stored in safes in a secure room at campaign headquarters for review by attorneys. Asked what was inside the safes, Myers replied "tax documents, everything we used.” And how many years? "Several" she said, declining to provide a more specific number.
