"It is not that it is not tactful or indecent, it is cynical and not humane. By any logic, he is politically dead. He must resign immediately. We definitely want to raise this issue everywhere, including in the media. Germany deserves better candidates," Breininger said.

Germany is set to hold a general election on September 26, after which a new government will be formed.
