Erika Kirk vowed in a September 12 speech to continue her husband’s movement and said that “the cries of this widow will echo around the world like a battle cry.”

It was Erika Kirk's first public appearance since her husband was killed while speaking with students at Utah Valley University days earlier.

“The evil-doers for my husband’s assassination have no idea what they have done,” she said in a livestream on the YouTube page of Turning Point USA, the conservative movement her husband started out of high school in Illinois that has since swept college campuses around the nation.

Kirk’s address came in the aftermath of authorities announcing that they had captured a suspected shooter in Kirk’s killing. Utah Gov. Spencer Cox told reporters later in the morning that Tyler Robinson, 22, was taken into custody after a family member contacted a family friend, who then informed authorities that Robinson had "confessed to them or implied that he committed the incident."

The mother of two spoke from her husband’s studio where he delivered The Charlie Kirk Show. The desk was outfitted with white hats with a gold number "47," a reference to President Donald Trump. The conservative talk show host was a strong proponent of the 47th president.
