FOX NEWS -- Soros, who is the son and heir to George Soros’ fortune and philanthropic empire, condemned the killings in an X post, saying "the murder of Sarah Milgrim and Yaron Lischinsky at the Capital Jewish Museum was evil in its most basic form" and that "this brutal antisemitic act must be condemned in the strongest terms."

Milgrim and Lischinsky, two Israeli Embassy staffers who were set to be engaged, were killed outside an event at the Capital Jewish Museum in Washington, D.C., on Wednesday night.

D.C. police identified the suspect as 31-year-old Elias Rodriguez, who was taken into custody after the shooting attack. He was allegedly seen pacing outside the museum before he approached a group of four people, including the two victims, and opened fire. Rodriguez then reportedly went into the museum, where he was detained by security. He allegedly shouted "Free, free Palestine!" while in custody.
