Dede Laugesen, president of Save the Persecuted Christians, revealed on Sept. 11 that Charlie Kirk — just hours before his assassination — had agreed to lead an event in support of persecuted Armenian Christians.

In a Facebook post, Laugesen, who leads a coalition promoting freedom and independence for Armenia—the world’s oldest Christian nation—announced that Kirk had promised to spearhead an upcoming prayer breakfast for Armenians threatened by the Muslim-majority neighboring country of Azerbaijan.

“Just hours before he was killed, Charlie had committed to be the keynote speaker for the first ever Republic of Armenia’s Prayer Breakfast in Armenia. As a member of the organizing team, we are devastated. There are very few who could fill his shoes,” Laugesen wrote.
