I hate defending a Trump mouth piece but any scan of the internet will show you that Hitler did not use chemical weapons during World War 2.  Both the Nazis and the Allies had large stockpiles available but neither side used what was available.  The Japanese did.

Using gas in the death chambers is not using gas as a weapon.  The Jews, male homosexuals, mentally disabled, Russian and other POW’s, Romani, clergy of many religions and others all died in the chambers but these murders were not used with what most consider weapons.

This mouthpiece can't express very well, but in this case his facts were real.
