Through Instagram, the country music star stated, "Our flag is flying a little lower here today at EH-OK Farm. I remember exactly where I was 20 years ago when a friend told me on my way to class what had happened. It was absolutely impossible to comprehend at the time the words that he was saying. To be honest, 20 years later, I still can't comprehend it. We must never forget September 11 and how it changed us as a country. We must remember those that had their lives stolen that day and continue to pray for their families who are still grieving. And we continue to be thankful to those who were there to help...and are still here to help. God bless America. #NeverForget"
