"Everything happened to get Tusk to halt being Prime Minister. He trusted people who jumped at their own funeral." Whose words are those?

These are any of the strongest words of criticism which have so far been made to Donald Tusk and people from Rafał Trzaskowski's staff. Interestingly, they were not expressed by any opposition politician, but by Deputy Marshal of the legislature and associate of the governing coalition of PSL Michał Kamiński.
