Kamala Harris praised Donald Trump's former chief of staff for sending a 911 call" to the nation about the former president's unfitness to serve a second term, attacking her opponent as a fascist" who would send the nation down a dangerous path.

Harris participated in a CNN town hall with undecided voters in Delaware county, Pennsylvania, on Wednesday, as the battleground state appears poised to play a potentially decisive role in the presidential race. While taking voters' questions on everything from the cost of living to abortion access, Harris repeatedly steered the conversation back to questions over Trump's fitness for office.
