I understand this is not the only case of this sort of potential conflict of interest with a judge/Justice and his/her spouse, but this seems like a problem to me. Clarence Thomas's wife is running a "tea party" group.
Justice's wife launches 'tea party' group
Because of a recent Supreme Court decision, Citizens United vs. Federal Election Commission, the group may also spend corporate money freely to advocate for or against candidates for office.
Justice Thomas was part of the 5-4 majority in that case.
Does Mrs. Thomas draw a salary from this organization? Is that salary funded by donations?
Oh, but don't worry, Justice Thomas is so squeaky clean he won't even come listen to the President speak:
Justice Thomas, 61, recently expressed sensitivity to such concerns, telling law students in Florida that he doesn't attend the State of the Union because it is "so partisan."
Except for maybe that time he helped Bush steal the election:
In 2000, while at the Heritage Foundation, [Virginia Thomas] was recruiting staff for a possible George W. Bush administration as her husband was hearing the case that would decide the election. When journalists reported her work, Thomas said she saw no conflict of interest and that she rarely discussed court matters with her husband.
