As the article is written, it appears that Merz responded to this question with a non-answer, as politicians will sometimes do. Instead of responding directly, he went on an extended tangent about German law on Holocaust denial, which applies to German immigrants as equally as to native Germans.

And to be clear the Holocaust these laws are about is a set of events that occurred in Germany and German-controlled territory from 1933-1945. It is illegal in Germany to deny the truth that 6 million Jews and a number of others were murdered by the government during that time.
