Dieu-Nalio Chery was hit in the jaw by what appeared to be a fragment of one of the bullets fired by Senator Ralph Fethiere on Monday morning.
Mr Chery was treated and released from a Port-au-Prince hospital and was expected to undergo further treatment this week to remove the object from his jaw. Another person outside the Senate also suffered an apparent wound to the stomach.
The incident occurred when Senators were convening Monday to approve Fritz William Michel’s nomination as prime minister.
Several hundred opposition supporters confronted ruling-party senators and Mr Fethiere pulled a pistol when protesters rushed at him and members of his entourage.
