reporter: paul whittington was in one of his classes at east carolina. >> he kept a running log of every single negative thing that a student said about him. one of the things that always stood out to

thank you. meantime tonight, does mark two months now since the hamas terror attack on israel. and this evening, a u.s. official now telling abc news that israel is considering flooding hamas' tunnels, where they believe militants and operatives are still hiding. abc's james longman in israel tonight. >> reporter: tonight, israel now considering a plan to flush out the tunnels under gaza, where hamas leaders are believed to be hiding. a u.s. official telling abc news they want to degrade hamas capabilities. possibly pumping in sea water to flood that underground network. and it comes as new video circulates online from gaza showing rows of men in their underwear with hands behind their backs surrounded by israeli soldiers, while others are loaded into military vehicles. israel says they captureded more than 150 hamas terror suspects in the north of the strip. we pressed the idf on the claims they are linked to hamas. who are these people? do you consider these to be terrorists or are they civilians? isr >> israel does not arrest, apprehend, or target anyone in the gaza strip that is not a hamas terrorist or poses an imminent threat to israel. >> reporter: mrthis palestinian correspondent was among those detained and demanding his release. we spoke to another man who lives in washington, d.c., he says he saw his brother in that video, and he says he's not a terrorist. >> it's a violation. this is my little brother, i know him. he is not involved in anything. they're not fighters, certainly they weren't surrendering, because they weren't doing anything. >> reporter: over 17,000 have been killed so far in gaza, according to the hamas-run health ministry. neighborhood after neighborhood destroyed. and in israel tonight, two months to the day since hamas launched the deadliest terror attack in israel's history, the nation is remembering the 1,200 people murdered. this manwoman's cousin is sayin the israeli government is not prioritizing the release of the hostages. >> we cannot wait anymore. we need to understand what's going on. we need negotiation, we need someone. we need something to happen. >> reporter: and tonight, as israelis join jews around the world marking the first day of hanukkah, the wounds are still raw. is there something about going into hanukkah when makes this period especially difficult or especially moving? >> i don't feel like the joy and the happen pins and the light of hanukkah. not when they are going through holocaust. i think this is the way to describe what they're going through, holocaust. so, i don't feel like celebrating hanukkah right now. >> david: now two months after this attack on israel. let's bring back in james. i want to go back to what you reported there on the hamas tunnels. a u.s. official confirming that israel is considering a plan to flood the tunnels, perhaps? >> reporter: yeah, and a lot of risks with that plan, david. flooding those tunnels would knock out water filter systems that provides drinking water to gaza, and could, of course, endanger those remaining hostages. david? >> david: james longman in tel aviv again tonight. thank you. back here in the u.s. tonight, another major storm slamming the northwest. and now a cross-country system that will then race right across the country and into the northeast, as well. senior meteorologist rob marciano back with us tonight to time all of this out. hey, rob. >> reporter: hi, david. this comes on the heels of that flooding storm. this one's got some punch, so, it will trek across the country. the radar is filled in over the afternoon from san jose to seattle. we saw over a foot of snow just east of us in tahoe. one to two feet. it's got a cold core socoming. and into the plains it goes on saturday. then it's got a severe weather component. starts to ramp things up, southeast texas, louisiana. could see tornadoes there. then the heavy rain pushes up into the northeast on sunday before moving out on monday. it will be a big mess for everybody east. david? >> rob marciano back with us tonight. thank you, rob. we turn now to texas tonight, and to the issue of abortion. tonight, the case of a young woman with her husband today, she's 20 weeks pregnant. her doctors say her own health is in danger because of complications now. going before the judge after being told in texas she still cannot have an abortion. tonight here, the judge's ruling, and how the state is now responding. here's rachel scott. >> reporter: tonight, a first of its kind case playing out in texas. in an extraordinary livestreamed court hearing, 39-year-old kate cox and her husband begging a judge to let her have an emergency abortion, ban under texas law. >> today, we are seeking a temporary retraining order to allow ms. cox to get the abortion she needs now. >> reporter: cox is 20 weeks pregnant. doctors have told her her fetus has a severe abnormality and virtually no chance of survival. what's more, they said continuing the pregnancy could put her health at risk, and prevent her from getting pregnant again. texas now bans abortion outright, with one narrow exception -- to prevent major bodily harm or save the life of the mother. kate told me she was certain that would apply to her. >> i could see in this case, surely, i would qualify for chemical shun. my doctor told me that i did not have that option in the state of texas, i was shocked. my husband, as well. >> reporter: so, today kate and her husband listened as her lawyer described how kate had been to the emergency room four times in just the last month. >> many of ms. cox's health risks will put her life in danger if left untreated. >> reporter: she argued the law in texas outlining exceptions is just too vague, calling it cruel and dangerous. >> now, a patient must be about to die before a doctor can rely on the exception. >> reporter: still today, the state insisting kate cox needs to provide more evidence to prove she qualifies. >> the plaintiffs have not shown they will suffer an immediate injury. >> reporter: but the judge ruling on the spot that kate cox could get the abortion she is seeking. >> the idea that ms. cox wants desperately to be a parent and this law might actually cause her to lose that ability shocking and -- genuine miscarriage of justice. >> reporter: the judge adding, the longer ms. cox stays pregnant, the greater risks to her life. it's unclear if the state will try to fight this ruling, but tonight, the texas attorney general ken paxton is threatening to go after any doctor who might try to perform kate cox's abortion, saying they could still face sere you penalties, including the loss of their license, and up to life in prison. even her own husband could be at risk on charges of aiding and abetting an abortion. david? >> david: rachel, thank you. we turn now to the race for the white house. former president trump back in court in new york, skipping last night's debate. and the four candidates who were on stage trail trump for the nomination biy 40 to 50 points. despite being so far behind, only one of them appeared to be willing to take on trump. here's jonathan karl. >> reporter: today, the split screen republican presidential primary campaign on full displace. in new york, front-runner donald trump was in hoosg to attend the civil fraud trial against his company. >> i think it's going very well. >> reporter: and in iowa, florida governor ron desantis trying to find some momentum after the fourth republican debate. >> great to be back in iowa. >> reporter: but once again, trump skipped the debate, leaving the candidates who did show up fighting each other instead of the front-runner. >> the fifth guy who doesn't have the guts to show up and stand here, he's the one who has, as you just put it, is way ahead in the polls. and yet, i've got these three guys who are all seemingly to compete with, you know, volume demort. they don't want to talk about it. >> reporter: former new jersey governor chris christie seemed to be the only candidate willing to take trump on at all. and the only one to address trump's comments. >> he says, you're not going to be a dictator, are you? i said, no, no, other than day one. >> do you think he was kidding when he said he was a dictator? all you have to do is look at the history, and that's why failing to speak out against him, making excuses for him, pretending that somehow he's a victim 'em powers him. >> reporter: desantis, instead, spent much of the debate taking on former south carolina governor nic can i haley, who has been rising in the polls, though both of them trail trump by double digits. >> nikki will cave to those big donors when it counts. and that is not acceptable. >> he's mad because those wall street donors used to support him and now they support me. >> reporter: ron desantis was asked again today about trump's recent remark that he would be a dictator on his first day in office. and once again, he had nothing to say about that or, david, about any of trump's other recent controversial comments. david? >> david: jon, thank you. when we come back here, the
