>> in the short term, i would say that the ticketing process could get more chaotic, and prices could go up. in the long term, one would hope it would make things better. >> reporter: last year, live nation raked in close to $23 billion, with 145 million fans going to live events. tonight, here at metlife stadium, unlike other concerts with sky-high ticket prices, these fans are getting what they want from the rolling stones. they can be in the audience for as low as 70 bucks. norah? >> norah: sounds like they will get some satisfaction. meg oliver, thank you. louisiana is now on the verge of becoming the first state in the country to reclassify two commonly-used abortion drugs as controlled and dangerous substances. cbs's caitlin huey-burns is here with the details. this is a big story. what does the bill do? >> reporter: well, this is supposed to be headed to the governor's desk. he's expected to sign it, and it is likely to make it -- it will make it illegal to possess mifepristone and misoprostol without a prescription in the state. that's punishable by up to ten years in prison and $75,000 in fines. now, this drug combination was used in more than half of abortions nationwide last year, and the fda says it's effective. >> norah: so, abortions are already illegal in louisiana, so what practical effect does this have? >> reporter: well, this could make it harder for physicians to prescribe the drugs, which are used to treat other conditions and to manage miscarriages. the reclassification would require doctors to have a special license to write a prescription, and the drugs would have to be stored in certain facilities. hundreds of doctors in louisiana say they oppose this because it could delay care, and louisiana has one of the highest maternal mortality rates in the country. and in the midst of all of this, we are awaiting a decision from the supreme court on mifepristone, which could impose a nationwide ban, and a decision on that is expected at the end of june, norah. >> norah: we'll be watching very closely. caitlin huey-burns, thank you so much. an american soldier is in critical condition at an israeli hospital tonight, injured in a forklift accident while working on the floating pier off the coast of the gaza strip. two other soldiers were also hurt in a separate accident, but they are expected to return to duty. and humanitarian aid is once again flowing from that u.s.-made pier, according to the united nations. deliveries were halted over the wekend after a convoy of trucks was looted by palestinians desperate for food and supplies. earlier this evening, police broke up a pro-palestinian protest on the campus of ucla. officers moved in after demonstrators set up tents and barricades, and then climbed onto the roof of a building and tried to lock officers out of another building. and earlier today, ucla's chancellor was testifying on capitol hill to the handling of campus protests and a rise in anti-semitic incidents. the presidents of northwestern and rutgers university defended their decisions to end pro-palestinian encampments through negotiations rather than police force. calls are growing for supreme court justice samuel alito to recuse himself from any cases that involve the january 6th assault, donald trump, and election integrity. and this comes after photos surfaced of provocative flags linked to the capitol insurrection being displayed at two homes owned by alito. cbs's scott macfarlane has the new developments. >> reporter: a political distress flag. tonight, more calls for conservative supreme court justice samuel alito to recuse himself from two pending cases involving january 6th, including on the question of whether donald trump can be prosecuted. >> the supreme court has chosen to conduct itself as if the judiciary is above the law. >> reporter: this amid reports by "the new york times" an "appeal to heaven" flag was flying last summer outside alito's new jersey vacation home. the flag represented the fight for independence during the american revolution, but it took on new meaning in 2021, when it was seen wielded on the front lines by january 6th rioters. the revelation came just days after alito acknowledged an upside-down u.s. flag, also carried by january 6th rioters, hung briefly outside his virginia home, days after the u.s. capitol siege. alito said he had no involvement whatsoever, that his wife hung the flag amid a dispute with neighbors. many republicans stood by alito today. any concern about there being a flag there? >> people who are judges on the supreme courts have personal lives, they have families, and i don't think they are necessarily responsible for everything their families do or say. >> reporter: and the g.o.p. is expected to block any efforts by democrats to pass new ethics rules for the high court, which has a code but polices itself. >> there is literally no place else in the federal government in which an allegation against an official is raised, and there is not even fact-finding done. >> reporter: new polling shows public approval of the court has plummeted in just the last four years. >> i think, at the very least, we need more answers to questions about the second flag and about his involvement and about whether he tried to distance himself from it because a flag outside of his house reasonably appears to represent his own views of the merits of the case. >> reporter: alito did not return our request for comment on the flag controversies, but he and the rest of the court are set to rule on two big cases related to january 6th and the 2020 election in the coming weeks, if not the coming days, norah. >> norah: scott macfarlane, thank you. the good news, it probably won't cost you more to travel this holiday weekend, but it's a different story when you get there. we'll explain. and later, "eye on america," young adults are less byob and more byoc -- bring your own cannabis. can't filter out the real you. so go ahead, live unfiltered with the one and only sotyktu, a once-daily pill for moderate to severe plaque psoriasis, and the chance at clear or almost clear skin. it's like the feeling of finding you're so ready for your close-up. or finding you don't have to hide your skin just your background. once-daily sotyktu was proven better, getting more people clearer skin than the leading pill. don't take if you're allergic to sotyktu; serious reactions can occur. sotyktu can lower your ability to fight infections, including tb. serious infections, cancers including lymphoma, muscle problems, and changes in certain labs have occurred. tell your doctor if you have an infection, liver or kidney problems, high triglycerides, or had a vaccine or plan to. sotyktu is a tyk2 inhibitor. tyk2 is part of the jak family. it's not known if sotyktu has the same risks as jak inhibitors. find what plaque psoriasis has been hiding. there's only one sotyktu, so ask for it by name. so clearly you. sotyktu. looking for a smarter way to mop?
