Campaign Press Release - Statement by Biden for President Deputy Campaign Manager and Communications Director Kate Bedingfield
Donald Trump doesn't make the debate schedule; the Debate Commission does. We accepted the three dates — Sept. 29, Oct. 15, and Oct. 22 — in June. Trump chose today to pull out of the October 15th debate. Trump's erratic behavior does not allow him to rewrite the calendar, and pick new dates of his choosing. We look forward to participating in the final debate, scheduled for October 22, which already is tied for the latest debate date in 40 years. Donald Trump can show up, or he can decline again. That's his choice."
