Le Pen is a a Vichy apologist and fascist. He wishes to mitigate their crimes in order to cleanse the sins of the collaborators and traitors.
Most of the Jews who were in France who wound up perishing were the refugees who either came from Eastern Europe or fled the Nazis. The French felt these “refugee” and “foreign” Jews were a burden, and were more than happy to let the Nazis take them off their hands.
However, they did consider French-born Jews to be Frenchmen and were not as willing to hand them over, and as a result, 75% of French Jews did survive the war, one of the highest rates of all of the occupied countries. Not to diminish the horrible crimes that Vichy committed, but it does show that the French were not all bad during the war.
