Mr Cruz is an a$$. The presiding officer may have been distant from other senators but unlikely to be distant from sergeant at arms, or other aides. Someone could walk up behind him with a question, comment or missive. He has to be ready for that at all times in that public setting. Further it is people like Mr Cruz who have put us in the position we are in today with raging out of control coronavirus cases. Just wear the damn mask Mr Cruz and stop acting like a baby. We wear masks to protect you, you can at least have the decency to wear a mask to protect others.
