Also today, secretary of state Antony Blinken left washington for his latest trip to the region. Blinken is expected into israel tuesday. It will be his seventh visit since the war began in october. Cbss debora patta is in East Jerusalem tonight with the very latest. Debora . Reporter good evening. There is a flurry of diplomatic activity in this region this weekend, a lastditch effort to revive ceasefire talks and secure a hostage deal ahead of a possible ground offensive in the Southern Gaza city of rafah. The pressure is mounting on Prime MinisterBenjamin Netanyahu. Anger over the governments failure to bring their loved ones home has spilled onto the streets, as demonstrators have stepped up their protests, which more than once have ended in scuffles with police. Prioritizing a hostage deal over the rafah offensive has exposed cracks in Netanyahus Coalition government. The release of the hostages is our first priority, said foreign minister israel katz. Adding that would mean deferring an offensive in rafah, where more than 1. 4 million palestinians are sheltering. A move vehemently opposed by israels more hawkish rightwing faction. With the threat of a fullscale offensive hanging over rafah, people here keep asking where will they go . Much of gaza lies in ruin. The destructs on such a scale it is uninhabitable. And there is nowhere safe to run to. This little boy and his elder sister are beside themselves with grief. Theyve already lost their mother. Now their fathers been taken too. My brother is just 6 years old, zayna al ref screams. Hes an orphan. How do i raise him. The staggeringly civilian death toll in gaza has sparked nationwide protests at american universities, which have not gone unnoticed by students in rafah, whose education came to an abrupt halt with the war. They no longer have walls to spray graffiti on. Instead showing their gratitude on the tents they now call home. Aid groups have warned that an invasion of rafah would worsen the already desperate humanitarian situation in gaza, jericka, where famine looms. Debora patta reporting in East Jerusalem. Thank you. In this country stantiwar protests on College Campuses have grown nationwide. This is usc in los angeles. Police there and in other cities made over 100 arrests this weekend. Cbss Mark Strassmann has more. Reporter while the clamor on campus keeps spreading, a clash of more than ideas. Riot gear at ohio state. Tasers at Emory University in atlanta. Mostly propalestinian protesters at times scuffling with police, waved on by school administrators, with hundreds of arrests. Communities like the university of texas turning on each other. Israels war on hamas has another front line. Free, free palestine reporter a free speech and hate speech campus debate thats anything but academic. If you want to protect free speech, then you dont break up peaceful protests. People didnt seem to be aware of how bad the situation was for free peech and Academic Freedom already was on campus until october 7th. Reporter Greg Lukianov of the foundation for individual rights and expression, a group defending the right to free speech. Do you have the sense that any of this is moving the ball forward . Some of the way the protests have been going on on College Campuses has been alienating more of the public than bringing it in. Reporter on Columbia Universitys west lawn civil disob disobedience. This ongoing tent city galvanized national protests. They want the university to divest investments in israel and companies they say profit off repression of palestinians. Dueling protests at columbia. Proisrael, propalestinian, reflect a larger welter of opinion and emotion, passion and perceived prejudice. People would be up in arms and protesting that right away. But because its the jews i feel like nobody cares. Reporter all this coasttocoast commotion is well into its second week. And what began here at columbia has now rippled overseas. From paris to London University students occupied buildings and marched in the streets. Theyre echoing this u. S. Student movement.

Announcer this is the cbs overnight news. Im Jericka Duncan in new york. Thanks so much for staying with us. Campus protests against israels war in gaza are expected to continue this week at colleges and universities across the country. Over the Weekend Police made hundreds of arrests at a half dozen schools. Administrators are grappling with how to balance free speech against complaints of intimidation and possible violence. So how did we get here . David pogue has that story. We want justice, you say how. Hands up. Bring them home reporter its been an upsetting week on american College Campuses. Oh, my god. Reporter clashes with armed police. Why are you doing this . Reporter mass arrests of students and outsiders. Locked campus gates. The firestorm began on april 17th, when a Congressional Committee grilled Columbia University president Minouche Shafik about antisemitism at student protests against the war in gaza. Antisemitism has no place on our campus and i am personally committed to doing everything i can to confront it directly. Reporter she promised to crack down on the protesters. And she did. For what reason . Im just standing on the sidewalk. Reporter the columbia news enraged students on other campuses nationwide. For many College Administrators its a nowin situation. It is presenting a near existential threat to the very fabric of the universities life. Reporter dan mogolov is a Public Affairs officer at the uft of california berkeley, where this weeks protests have been peaceful. These campuses are supposed to be areas for free speech. We have an unwavering and absolute commitment to free speech. But the University Like all Public Institutions is allowed to have time, place and manner rules. Meaning the right to Free Expression is not absolute. You cant interfere with or disrupt the operations of the university. Reporter and thats the problem. Many colleges say that the protests violate those time and place rules and make other students feel unsafe. Including skyler saradsky, a senior at George Washington university in washington, d. C. I was here a little bit earlier with a few of my friends holding the israeli flag that im now wearing, and i got spit at. We got middle fingers from a few people. We took over a Campus Administration building. We occupied it, threw the deans out of the building. Reporter as a selfdescribed radical at harvard in the 60s, Michael Kazan protested the vietnam war. Today he teaches the history of social movements at Georgetown University in washington. Do you look back fondly on your protest days . We felt we were changing history. And in some ways we were. And thats a thrill. One of the reasons i became a historian is because i was involved in these movements. Are there any ways that the current conflict is different from the previous ones . Well, the most important one from vietnam is that american soldiers are not fighting. American planes are not bombing gaza. Reporter another difference . This time the students arent unified against a common enemy. The middle east is unique in that it divides the campus community. It sets student against student, faculty member against faculty member. And then all of that is fueled in a way it never was in the past by social media. Reporter so what exactly do these protesters want . Our goal for georgetown is for georgetown to divest. I want to stay here until like like the university divests. We mean divestment. Absolutely. Got it. Reporter a colleges endowment is a taxexempt fund it can use to pay for professorships or scholarships. Every college invests its endowment. But the protesters want these schools to sell off the stocks in companies that benefit from the war like weapons makers or that do busines with israel. But for a big school that could be hard to do. The modern endowment is invested in huge portfolio funds that dont offer control over individual stocks. Do these students think that divestment will actually make a difference in anything . And will it . No, probably not. I dont know what percentage goes to a company that does business with israel. But it probably isnt very much. But its a way to make demands on people they might have some influence over. Which are College Administrators. Theyre not changing the course of the war. But they are also in effect asking a question of college administrations. Do you see me . Do you hear me . Do you care about me . Reporter some tactics definitely dont say we care about you. One thing we did learn in the 60s, though, is that bringing in the police, arresting students is almost always a bad idea. Unless theyre violent. Sending in the cops is the best way to make sure its not going to be peaceful. Reporter and thats not the only pattern kazan has observed. April is the month for protests. It was back in 1969. That was true in 1986. What do we want . When the antiapartheid protests were at their height. Its before final exams. The weather is nice in most parts of the country. Reporter but in other ways april couldnt be worse timing because graduation is only weeks away. The university of Southern California has already canceled its main commencement ceremony. And other schools may follow suit. And remember, this years graduating seniors already lost their High School Graduation ceremonies in 2020 to covid. But for demonstrators like George Washington junior riley bukema the protests take priority. So missing two graduations has to be a really sad prospect. And i know thats a really tricky position. But its not as tricky as being bombed. So i feel like this is more important. Do these protests sometimes work . It can work in getting attention and effectuating a certain degree of change. How much . Debatable. But that doesnt make it less important to those engaged in it. Reporter georgetown sophomore and protest organizer selena al shihabi is more confident. If you look back at history, its all the student movements. It always starts with the new generation waking up and saying we will no longer tolerate this and we are going to create a better tomorrow for our children to live in. And thats what were seeing right now. That again was david pogue reporting. Well, in washington the clock is ticking on tiktok. Millions of users including Small Businesses are threatened by a new law that could ban the chineseowned platform altogether. Jo ling kent has more. This is where you go live from. This is where i go live from, yeah. We support every business on here. Reporter Brandon Hurst says tiktok has changed his life. It allows me to go live, share who i am. But it also makes it easy for people to buy. Reporter since he started selling on tiktok last year hurst, better flown as brandon the plant guy, says hes tripled his business. In the last year weve been able to sell 57,000. Everyone always asks me do i have a favorite variety of antiyes, i do. Reporter his company is one of 7 million Small Businesses on tiktok. According to the platform, it has supported more than 224,000 american jobs. I have friends and family members that work for me and help package plants and orders. So this goes beyond just me now. This is like a team of eight other people that would lose their jobs. Reporter now that the tiktok ban has been signed into law, the chineseowned social Media Company has nine to twelve months to sell to an american owner or be banned. Forcing scores of entrepreneurs to look for a new home. In the meantime, tiktok plans to sue in federal court. One of the biggest beneficiaries of a tiktok ban of course would be meta. Instagram reels is the most natural fit. It isnt exactly the same. You can replicate the technology but you cant replicate the culture. Where do you pivot your social Media Business . Im on instagram. Ive been doing business on other platforms. Theres just not many places you can live sell. I havent thought about it yet, to be honest. Im not sure. Im not sure what well do. We just hit 225,000 likes. Reporter an uncertain future for his budding business. Bytedance, the Parent Company of tiktok, says it has no plans to sell the company. Meanwhile, tiktok ceo sho chu is leaning on the companys recent First Amendment victories in u. S. Courts, vowing it will prevail again. Jo ling kent, cbs news, los ageles.
