Trump should say he wants the debates to Be moved up to this week, and Some way suggest the reason is Biden want to cancel debates and/or replace Biden by the September (Make it vague). There is Enough time that something could (and will) happen to Biden for him to not debate. Biden was also in that “socially distanced circle” for Labor Day, so they can’t lie about him not going near people. Finally, Trump can Ask Biden to take off his mask, saying how he can’t hear him, because he recently did that.
