Since 2004, Thomas has accepted more than $4 million in donations, much of it undisclosed and only revealed thanks to dogged reporting by ProPublica and others. That is more than every other justice who has served on the court over those same years – combined. As MSNBC economic analyst Steve Rattner commented: “One of these justices is not like the others.”

According to data compiled by Fix the Courts, a nonprofit that advocates stricter ethical rules for the nation’s highest judicial body, the justice who accepted the second most gifts, the deceased Antonin Scalia, came it at just over $210,000; Samuel Alito, coming in third, took $170,000.
