Boris Johnson, the leader of the British exit campaign — "Brexit" — offered his condolences on Cox's death.

Leader of the U.K. Labour Party Jeremy Corbyn said, "The whole of the Labour family, and indeed the whole country, is in shock and grief at the horrific murder of Jo Cox."

Gabrielle Giffords, former Arizona congresswoman who made headlines when she became the victim of an assassination attempt, tweeted about Cox's murder.

"Absolutely sickened to hear of the assassination of Jo Cox. She was young, courageous, and hardworking. A rising star, mother, and wife," Giffords said.
