In his central capacity as the leader of Young Alternative, AfD-youth organizsation, Frohnmaier started to be in contact with Russian youth groups at the latest in 2016. He had met Robert Shlegel, Duma deputy as well as high-up functionary of United Russia, in order to "explore what form of cooperation could be possible" with United Russia’s youth organisation, the Young Guard. These discussions were continued in December 2016, when Frohnmaier met with the international secretary of the Young Guard, Daria Sharova, in Moscow. A document from the Russian mission in Germany indicated that Frohnmaier was supported by the Russian authorities and that they are quite positive about, if Frohnmaier got elected. According to German media recherches, the decision to help Frohnmeier and in return receive favours from him came directly from the Russian president, Vladimir Putin. Frohnmeier has denied the allegations, after the reports. Politicians from the Christian Democratic party have called Frohnmaier to step down after reports indicated, that he was working under the influence of the Kremlin. In March 2019, Frohnmaier became a member of the FSB Organizing Committee of the Yalta International Economic Forum, an economic forum in the Crimea sponsored by the Russian Government. Frohnmaier said in 2016 in an interview with public broadcaster NDR, that crimea belongs to Russia. As the reporter aksed again, he added "from an historic view."
Political positions
Tom Thieme analysed at bpb in 2019 if AfD is a far-right party and concluded that their "fundamental criticism of Germany's democratic system goes hand in hand with a decidedly ethnocentric anti-pluralism." He referred also to Marcus Frohnmaier, who said before he became a member of the Bundestag: "I say to this left terrorists...: If we come, then it will be cleared up, then it will be mucked out, then politics will be done again for the people and only for the people - because we are the people, dear friends." In its 2019 report on the AfD, the Federal Office for the Protection of the Constitution made the conclusion, that Frohnmaier legitimizes "attacks on the state monopoly on violence", that he has "connections to right-wing extremist publishers / publicists" and to the "Islamophobic German Defense League". Frohnmaier flatly defames refugees, for example as a "rag proletariat", and advocates massive unequal treatment and categorical suspicion of refugees, for example with the demand for a blanket "curfew" for all refugees under 50 and for religious discrimination against Muslims. Frohnmaier also calls for the Federal Constitutional Court to be replaced by partisan judges should the AfD take power. The Office for the Protection of the Constitution certifies that Frohnmaier's claims “violate the guarantee of human dignity of Art. 1 GG” and are therefore unconstitutional. The expert opinion led to the classification of the entire AfD as a test case and the classification of the "Young Alternative", whose chairman Frohmaier was for a long time, as a suspected case.
