Only these are listed for Trump and to my knowledge none of the above have done so.

he Wall Street Journal (January 2021): Following the January 6 attack on the U.S. Capitol, the conservative editorial board called on Trump to resign immediately. They stated that his conduct "crossed a constitutional line" and that his departure would prevent a second impeachment.
The Connecticut Post (September 2019): The largest newspaper chain in Connecticut published an editorial demanding Trump's resignation over his communications with Ukraine, which led to his first impeachment.
The Portland Press Herald (June 2020): During a presidential visit to Maine, the editorial board released a piece calling for Trump's resignation due to his handling of the COVID-19 pandemic, record unemployment, and racial justice protests.
The Gazette (Cedar Rapids, Iowa, January 2021): After the Capitol attack, this paper's editorial board called for Trump to resign, citing his inability to lead and his role in inciting the violence.
