The incident came just days after AfD's other co-leader, Alice Weidel, cancelled a public rally due to concerns that her family would also be attacked.

Andreas Aichele, a spokesman for the Upper Bavaria Police Department, said it remained unclear whether the politician had been attacked, had fallen, or was simply not feeling well.

[1] In the German federal election the following year, he defeated Michael Kretschmer (later Minister-President of Saxony) in the electoral district of Görlitz.

[10] Ahead of the 2021 German federal election, Chrupalla was the AfD's leading candidate for the Bundestag alongside Alice Weidel.

[11] The German newspaper Die Zeit has characterised Chrupalla as one of the relatively more moderate members of the AfD's faction in the Bundestag.

[13] In February 2020, in the run-up to the 75th anniversary of the Bombing of Dresden in World War II, Chrupalla cast doubt on the figure of around 25,000 fatalities determined by a commission of historians headed by Rolf-Dieter Müller between 2004 and 2010.

[16][17] In June 2021, Chrupalla traveled to Moscow with several other AfD MPs to mark the 80th anniversary of the Wehrmacht's attack on the Soviet Union and laid a wreath there.

"[18] During another visit to Moscow a few weeks later Chrupalla – at the invitation of the Russian Defense Ministry – gave a speech at a conference in which he spoke of the Western Allies' "psychological warfare" right after World War II.

He alleged that the Allied victors' reeducation (de) of ordinary Germans after the war had had a lasting impact on the country's national identity.

[22] In the same talk show, Chrupalla suggested that the destruction of the Nord Stream pipelines was benefiting the USA in a way that he found suspicious, as they had an interest in selling expensive gas to Germany.

Chrupalla had previously explained Russia's aggressive warfare in Ukraine by saying that "every reaction results in a counter-reaction" and that Putin reacts to Ukrainian strikes like the destruction of the Crimean bridge.

But the “Americans have stayed and are keeping our country economically dependent – to the detriment of the citizens.”[27][28][29] At a speech by Ukrainian President Volodymyr Zelensky in the Bundestag in 2024, Chrupalla and Weidel declared that they refused to "listen to a speaker in camouflage".

[33] In November of that year, Chrupalla and his fellow Bundestag AfD member Petr Bystron met with Milica Đurđević Stamenkovski, leader of the Serbian far-right party Oathkeepers.

When the moderator, Andreas Wunn [de], stated that ICU doctors had confirmed that some 80 to 90 percent of COVID-19 patients in intensive care units were unvaccinated, Chrupalla claimed that such figures were unconfirmed.
