Witkoff said he had worn the necklace for more than 25 years and now wanted Alexander to wear it in his son’s memory.
The assassination attempt occurred as the Israeli delegation for hostage and ceasefire talks arrived in Qatar on Tuesday evening.
"When you argue between yourselves, when you're disbanding as a society, do you know who's watching? Hamas," Witkoff told hostage families.
Steve Witkoff told The Jerusalem Post he hopes the deal that freed Edan Alexander from captivity is a beacon of hope for everybody else.
Israeli-American Edan Alexander was released by Hamas on Monday following 584 days in captivity in a hostage release deal secured by US President Donald Trump.
Trump’s interest might only be in freeing Americans, and for that, we can thank him for the blessed release of Edan Alexander.
The president's arrival in Saudi Arabia will take place just one day after Trump's Middle East envoy, Steve Witkoff, helped facilitate the release of Alexander.
