before hamas put him on the back of a pickup truck. what those parents told our terry moran just today. and tonight, on this potential breakthrough involving hostages, president biden optimistic, saying he believes it's going to happen. abc's terry moran leading us off from washington tonight. >> reporter: in the shadow of the u.s. capitol, the march for israel demonstration extended far down the national mall, thousands gathered in solidarity with israel. from the stage, families of some of the hostages held by hamas in gaza pleading for their safe return. >> bring them home! bring them home! bring them home! >> reporter: and tonight, word that a possible breakthrough on a deal to release more hostages could come within the next 48 to 72 hours, according to a senior israeli source. president biden sounding optimistic. >> i've been talking with people involved every single day. i believe it's going to happen, but i don't want to get into detail. >> what's your message to the families? >> hang in there. we're coming. >> reporter: here on the mall, though, it was a time to show strength and pride. this huge crowd stretching almost to the washington monument, thousands of people, the blue and white of the israeli flag, and the red, white, and blue, and the chant going up for the hostages, "bring them home." at least ten americans are still missing, including 3-year-old abigail mor-edan, who was taken hostage at kibbutz kfar azza. abigail was still in her father's arms when he was shot dead by terrorists. >> abigail's mother and father were killed that morning. >> reporter: she's now alone in gaza? >> she's now alone in gaza. >> reporter: among those american hostages, 23-year-old hersh goldberg polin, who was taken by hamas at that music festival. we met his parents two days later in israel. rachel and jonathan showing david a picture of their son, huddling with others in a bomb shelter. hersh missing part of his arm after terrorists threw a grenade into that shelter, then ordered him into the back of a pickup truck. his parents are left with their son's two final text messages, saying, "i love you" and "i'm sorry." >> the fact that he didn't just say "i love you," but that he said "i'm sorry," i took immediately he knew we were going to be in tremendous pain or worry or crisis, because it's -- it made no sense, there's no other reason to say something like that. so that's the last time that we heard from him. >> david: and those two words, "i'm sorry." >> yeah. and i keep saying, "it's okay." >> reporter: 39 days later, rachel and jonathan are living a nightmare, still fighting every way they can for their son. when you spoke with david, you said you're sending your strength out every day to him. >> oh, yeah, for sure. and i -- it's a mantra i say all day long. i just say, "i love you, stay strong, survive." and i just say it, and then sometimes, i do it to myself, because it's so hard, it's not describable, it's not imaginable, even to me, what we're going through. so, i have to stay strong and i # have to survive. it's the only way we'll save him. >> david: and so let's bring in terry moran with us tonight. and terry, i'm so glad you met up with hersh's parents again, they are just so incredibly strong, like all of these families, and i know you're learning tonight that the families of the american hostages, including hersh's parents, will soon meet with the biden administration's top hostage negotiator? >> reporter: david, that meeting will take place tomorrow, and as you say, hersh's parents will be there. they told me today that they are still not getting any information about their son, hersh, and yet they still have hope, as you could sense there. we can also report that secret talks about this hostage deal have been going on for weeks, with hamas demanding there should be a days-long ceasefire in exchange for the release of any captives, and israel is saying there will be no deal at all unless dozens of their citizens are allowed to come home. david? >> david: terry moran leading us off tonight from washington. terry, thank you. there is also news coming in tonight from u.s. authorities on hamas. operating beneath hospitals in gaza. and what the u.s. now believes hamas is doing in those tunnels right now. tonight, the white house revealing u.s. intelligence confirms

now. >> reporter: tonight, the israeli military confirming it is raiding al shifa hospital, israel's largest hospital where the military says hamas was operating inside and underneath the biden

army and hold hostages. >> they have weapons stored there and are prepared to respond to an israeli military operation against the facility. >> reporter: the pentagon saying the assessment is "based on a variety of sources," but did not provide additional details. and back inside gaza, amidst that fierce street hospital, we were taken to rantisi children's hospital, where israel claims hamas had a command and control post in the bombed-out basement. those ak-47s look pretty old and rusty. i mean, was this a crack force that was here? >> no, no. some of the gear was operational gear, but also some of the terrorists fled away, did not stay here. it shows us the war machine hamas is conducting from hospitals. a hospital for children. >> reporter: israel's chief military spokesman showing us another room where they believe hamas kept some of the hostages. but the hospital's director tonight denying israel's claims, saying the facility was used for displaced families, not hostages. >> reporter: david, the israeli military saying it had given hamas a 12-hour ultimatum before the raid. no confirmation yet from the israeli military. that as a senior administration official tells us that the tunnels beneath al shifa are extensive and multilayered. it is believed there are hundreds of hamas fighters inside, with communications equipment and booby-traps, and the tunnel we saw, just outside that children's hospital, appeared to be very sophisticated. the israeli military telling us it was powered by a nearby array of solar panels. david? >> david: matt gutman in tel aviv for us.

congressman tim burchett says former speaker kevin mccarthy elbowed him in the kidneys today. during an interview with npr, the audio caught on tape. >> what kind of chicken move is that? you're pathetic, man, you are so pathetic. it was deliberate. it was just a cheap shot by a bully. >> reporter: did you elbow him? >> no, i did not elbow him. i would not hit him in the kidney. >> reporter:
