"The reason why we are overrun by culturally foreign people such as Arabs, Sinti and Roma is the systematic destruction of civil society as a possible counterweight from the enemies of the constitution by whom we are governed," the newspaper quoted the email as saying.
The email described German Chancellor Angela Merkel's government as "pigs" who were nothing more than "puppets of WWII allies." It continued to say Merkel's government was given the task of limiting the population of the German "Volk," or people.
The email's original text in German uses several words with strong Nazi-era connotations, including "Überfremdung," which roughly translates to "foreign infiltration" and is used in far-right circles to stir xenophobic sentiment.
Prior to the email's release, Welt am Sonntag said Weidel tried to stop the report from being published. The paper was contacted by Weidel's lawyers, who said the AfD politician was not the email's author.
Her lawyers told the paper that it was incorrect and unlawful to "publically claim that our client wrote this text or to even express that suspicion."
Weidel's populist party also backed her. AfD spokesman Christian Lüth told German news agency DPA that Weidel had assured him that she did not write the email, calling it "a fake."

Several days later, however, Alice Weidel changed her tune. She no longer claimed the mail was a fake, confirming the Welt am Sonntag, which had said it had an affidavit and other statements from people who were part of Weidel's personal and professional network at the time that proved the mail was not a fake.
