“Fifteen years ago, as a firefighter, I was part of the response to the Sept. 11 attacks against our nation. That attack and this year’s election may seem unrelated, but for me the relationship becomes clearer every day.

George W. Bush is an imperfect man, but he led us through the tragic days following the attacks. His leadership showed that America was a great nation. That was also the last time I remember the nation united. I watch Mr. Trump fail to unite America and drive a wedge between us.”
