The actual address begins with the president announcing his signature on the Equal Access Act, a key plank in his reelection campaign: “My fellow Americans: I’m pleased to tell you that today I signed legislation that will allow student religious groups to begin enjoying a right they’ve too long been denied—the freedom to meet in public high schools during nonschool hours, just as other student groups are allowed to do.”
It was prior to the speech itself, while the president was joking with the National Public Radio audio engineers during soundcheck, that he riffed on his own speech, saying:
My fellow Americans, I’m pleased to tell you today that I’ve signed legislation that will outlaw Russia forever. We begin bombing in five minutes.
