Families of the hostages held in Gaza demanded answers after President Donald Trump said “probably” fewer than 20 of the remaining hostages were still alive.

At a World Cup announcement in the Oval Office Friday, Trump said he “got a lot of people” out of Gaza, taking credit for a ceasefire deal that was negotiated by the Biden administration. “So now they have 20 [living hostages], but the 20 is actually probably not 20 because a couple of ‘em maybe aren’t around any longer.”

Trump’s comments drew an angry response from the Hostage and Missing Families Forum, which released a statement demanding an update.

“Mr. President, there are 50 hostages. For us, each and every one of them is a whole world,” the forum said in a statement released Friday evening. “If Minister [Ron] Dermer — who speaks only with the Americans but does not speak or meet the families of the hostages — knows otherwise, he should first update the families. It is our sacred duty to prevent further sacrifice and to bring everyone home.”

The statement references Ron Dermer, one of Prime Minister Benjamin Netanyahu’s close confidants. The forum has repeatedly asked for a meeting with Dermer.

After Trump’s remarks, Netanyahu’s hostage coordinator sent a message to the hostage families on Friday evening insisting that Israel’s information has not changed.

“According to the information in Israel’s possession, there is no change from the information you have previously received from us: 20 of the hostages are alive. Two are in critical condition, with grave concern for their lives,” said the message from Gal Hirsh, which was obtained by CNN.
