Dear Editor:

I believe that as a responsible, independent newspaper you have an obligation to demand from the writers to your editorial board factual information. Unfortunately, on at least two occasions, in letters to your editorial board, Mr. Mirchuk (January 17) and Mr. Martyniuk (January 29) made unsubstantiated, provocative allegations against our president, Joe Biden. They claimed that he blocked Ukraine’s military response to the Russian annexation of Crimea.
