More than a hundred members of the Special Forces community signed a letter of endorsement for Republican presidential nominee Donald Trump that was delivered by hand to Trump Tower in New York City on the 15th anniversary of the 9/11 terror attacks. The President and founder of the Kilroy Rising Political Action Committee Scott Kesterson delivered the letter at exactly 8:46am, the same time that the first plane struck the World Trade Center in 2001.

“This letter is significant because these aren’t people who usually weigh in on politics,” Kesterson told Breitbart News after delivering the letter. “Members of this community value their anonymity and that so many were willing to sign this letter shows just how critical this election is for the safety and security of our nation. I hope people will understand the magnitude of this letter and the people who signed it before they make their decision who to vote for.”

In the letter, Kilroy Rising PAC describes itself as “Special Operations veterans political action group,” and frames the election between Trump and former Secretary of State Hillary Clinton as a choice between having a nation and globalism. “Donald Trump is campaigning to secure our borders and maintain our sovereignty while Clinton is part of the open-borders globalist crowd,” Kesterson continued. “Without borders, we don’t have a country.”

The letter also cites General Mike Flynn’s support of Trump as another reason the group is endorsing Trump. The letter calls Flynn “one of America’s great generals,” and a man of “unquestioned integrity and loyalty.” Kesterson stressed the importance of the non-commissioned officers who signed the letter saying, “getting the endorsement of generals is great but to have so many Sergeants sign this letter is something special. They are the tip of the spear.”
