I'm not certain if Billy is attempting to take a jab at Trump for misspeaking, or if Billy made a typographical error. During this video, Trump mentions the 9-11 at the 2:13 point, and at no point mentions 7-11. Even if he had, why do Libs care so much about such things?
When Nancy Pelosi said "I’m, I’m, I’m investing in something I believe in. I believe in natural gas as a clean, cheap alternative to fossil fuels. … These investments in wind, in solar and biofuels and focus on natural gas, these are the real alternatives.", I didn't hear any Liberals address her ignorance, and ignorance is far worse than misspeaking.
