Given the conflict of interest, that would certainly not be out of bounds.
Some folks on this forum would still excoriate him for that.
To be honest, I would have preferred to see him eliminate the conflict of interest by dropping his own lawsuit. Mandating masks in the House chambers was idiotic, but there's no way to get around the fact that the House can make its own rules like that. If the House votes to require all of its members to wear New York Yankees uniforms on the House floor, then Massie has no legal/constitutional basis to oppose the measure.
