The California Democrat said on Friday her concerns have nothing to do with the Democratic nominee, noting she has no doubt Biden would be "excellent," but rather Trump's relationship with the truth.
"I just think that the president has no fidelity to fact or truth and actually in his comments the last few days," Pelosi said on Morning on CBS. "No fidelity to the Constitution of the United States. He and his henchmen are a danger — with their comments — are a danger to our democracy."
"Why bother?" she added.
Biden declining to show up would give Trump and his allies more ammo to attack the former vice president for "campaigning from his basement" during the coronavirus pandemic. On Thursday, Trump mocked Biden for calling a "lid" on public activities before 9 a.m.
