 Following the 2017 German federal election, the CDU/CSU parliamentary group decided against including Fischer in its list of nominees for Germany's new 18 person-strong delegation to PACE; the decision has been linked in media reports to his alleged role in limiting PACE's efforts to hold the Azerbaijan government under Ilham Aliyev accountable for human rights abuses as well as possible corruption.In early 2020, Fischer co-founded an informal cross-party group of MPs from the CDU, CSU and FDP parties who opposed a potential coalition government between CDU/CSU and the Green Party.In response to the Greek government-debt crisis, Fischer and Rüdiger Kruse proposed in 2015 that German holidaymakers whose holiday spending helps boost the Greek economy should be reimbursed 500 euros by the German state on their return, on condition that the hotel and restaurants they visited have paid their taxes.
