"Donald, I do hope you'll reconsider, to meet me on the debate stage," Harris said directly into the camera during her speech. "Because, as the saying goes, if you've got something to say, say it to my face."

Trump has he will participate in a Sept. 10 debate hosted by ABC News that he had agreed to when Biden was the likely nominee. In an interview Monday night, Trump said "the answer's yes," before adding "But I can also make a case for not doing it."

Harris' economic pitch on Tuesday closely echoed Biden's, for the stubbornly high cost of living that has darkened voters' for the past two years.
