The four democratic congresswomen told by President Trump to go back where they came from have said his comments are a racist distraction from his failing policies. In a joint news conference, the women, who are from ethnically diverse backgrounds, strongly criticised mr trumps stance on immigration. Here is our washington correspondent david willis. Facing accusations of racism and xenophobia, President Trump is not backing down. Spelling out his message and capital letters, lest anyone be in any doubt, and going on to attack the democrats for closing ra nks to attack the democrats for closing ranks around the four women. The democrats were trying to distance themselves from the four progressives, he wrote, but now they are forced to embrace them. That means they are endorsing socialism, haight of israel and the usa. Minutes later, at a joint news conference, the congress women, three of whom were born in the usa, hit back. He is launching a blata ntly hit back. He is launching a blatantly racist attack on four duly elected members of the United States house of representatives. All of whom are women of colour. This is the agenda of white nationalists. The first note that i want to tell children across this country is that, no matter what the president says, this country belongs to you. And it belongs to everyone. Some people think its controversial. A lot of people love it, by the way. The speaker of the house of representatives have said she will introduce a resolution condemning President Trumps remarks. But, while some republican lawmakers have been critical, the silence from senior members of the party has been deafening. I republican friends, he is not backing off. Where are you . When something this serious, this bigoted, this un american happens. You are making a deal with the devil. The question now for more moderate republicans going into next yea rs moderate republicans going into next years president ial election is what constitutes a crossing of the line. We will have more on that story and how the global media is reacting to that discussion later in news briefing. Lets brief you on some of the other stories making the news the Un Refugee Agency says it is deeply concerned about a new, stricter asylum rule due to come into force in the United States on tuesday. It says the measure curtails basic rights and isnt in line with international obligations. The number of people around the world going hungry has increased for the third consecutive year. In their annual assessment, un agencies say more than 820 Million People do not have enough to eat. At the same time, the report notes that obesity is also increasing globally. Anti Terrorism Police in northern italy have seized an air to air missile and other sophisticated weapons in raids on far right extremist groups. Neo nazi propaganda was also seized and three people arrested. The raids followed a year long investigation. It is expected that figures released later will show there were more than 1,000 deaths caused by drug abuse in scotland last year. There are estimated to be 60,000 problem users in the country. It already has the worst record for reported drug deaths in europe. Two years ago, twin sisters safa and marwa were born in pakistan, joined at the head. It is a very rare condition. Now, surgeons at great 0rmond street hospital in london have successfully separated the girls, with surgery so complex it had to be performed in stages, with a huge team, over more than 50 hours. In the first of three reports this week, our medical correspondent fergus walsh and producer Rachael Buchanan have had exclusive access to the family and the surgery. Joined at the head, safa and marwa have never seen each other. This is the start of an incredible journey, aimed at giving them independence. Its october 2018, at great 0rmond street hospital. Their mum has been praying for this day for nearly two years. Safa and marwa are what is known as craniopagus twins. Their skull is one long tube. Its incredibly rare. The 21 month old girls have separate brains, but these are misshapen. One, two, and three just come up. The surgery is so complex, it will happen in three stages over several months. The twins wont be physically separate until the final operation. So the artery from safa going to supply marwas brain has been clamped. Each twin is supplying the others brain with blood. Cutting these connections is dangerous, and will take two operations to complete. The twins are from pakistan. Ideally the surgery should have been done a year earlier, when healing ability is strongest, but there were delays finding a donor to pay the medical costs. Despite the risks, the family and doctors believe it is right to go ahead. If we felt there wasnt a very high chance we could do it safely, we would be thinking quite carefully about whether we should do it or not. I think the whole team feel that theres an excellent chance of a successful separation here. A month after the first operation, the twins are back in theatre. Surgeons have to finish separating their shared blood vessels. Theres something oozing deep down there that i cant see at the moment. But marwas heart begins to fail. They fear losing her. Do you have a pulse or not . Were not stable, but we are less unstable. Good enough for me. The crisis passes. Because marwa is the weaker twin, the surgeons give her a major blood vessel, to increase her chances of survival. But it disadvantages safa. Shortly after the 20 hour operation, she has a stroke. We were very close to losing her. She stayed in that critical state for a8, 72 hours after the surgery. It was a very difficult time for the girls, their families, and the entire team looking after them. But, after a lengthy time in intensive care, both twins pulled through. The next challenge will be to separate the girls. Fergus walsh, bbc news. An incredible story, and we will have the second half on the briefing tomorrow. Facebook says it wont go ahead with the launch of its libra crypto currency until regulatory concerns are addressed. Later today, the social media giant will face some tough questions from us lawmakers in congress over how its new Digital Currency will be governed. Us treasury secretary Steve Mnuchin expressed his fears on monday, saying libra could be misused by money launderers and terrorist financiers. James hughes from axitraderjoins me now. Good to see you. Ever since they announce the launch or the intention to have a Digital Currency, they have had just so much backlash from regulators. We mentioned Steve Mnuchin, but also jerome regulators. We mentioned Steve Mnuchin, but alsoJerome Powell, the head of the us central bank. There isa head of the us central bank. There is a real worry about how this will work. Absolutely, there is a worry about how this will work from facebooks point of view but it is not just the facebooks point of view but it is notjust the facebook crypto currency that gets this reaction from the us. The fed and Jerome Powell have been concerned about crypto currency in general. Point is the most well known, and trumps comments on the last few days, Steve Mnuchin and nowJerome Powell, we have seen libra fall, and other crypto currencies as well. The reason why these are so interesting and are willing to buy them is because there is that no centralised area, that there is almost a lack of regulation, which is what is attractive about these things. Now, theissue attractive about these things. Now, the issue with crypto currencies, and this will be the issue for facebook, is you have to walk the tightrope of having some regulation, but not too much regulation, to take away from actually what the crypto currency is for in the first place. So it is a real balancing act that has to be done by the us. The us are a lwa ys has to be done by the us. The us are always very. Not necessarily behind in these things, but they are a lot more wary. We have had financial crises which have been particularly painful in the us, so there is a lot that happens here, and there is a really fine line between regulation and actually letting these things run the way they are supposed to. And of course, libra and bitcoin and various other Digital Currencies are working on this technology called block chain, and it is interesting how President Trump was saying if facebook want to runa bank, trump was saying if facebook want to run a bank, they have got to be regulated in the same way that a bank is regulated. And this is the big discussion, isnt it, globally. How are these Digital Currencies policed . In the same way that how do you Police Facebook . Exactly right, this is the problem. And facebook itself has a lot of bad press from the us. We know that. Mark zuckerberg himself has been in front of the Senate Committee before. We didnt go necessarily to well for him that time, and with them being back there again, it is another big discussion. And i have been asking james to think about his most embarrassing or silly online purchase. We have all been there. I will share mine a bit later as well. Events will take place across the us today to mark 50 years since nasa sent the apollo 11 space rocket to the moon. The commemorations will focus on the Kennedy Space centre, in florida, where the mission was launched in 1969, an event that inspired millions of people who watched it all unfold on television. Tim muffett reports. We choose to go to the moon and do the other things not because they are easy, but because they are hard. President kennedy wouldnt live to see his dream fulfilled, but injuly 1969, 600 Million People watched in wonder. Tranquillity base here, the eagle has landed. When it landed, we also have jumped up and shouted we did it. Keith wright, who now lives in dorset, had good reason to be thrilled. This is me inside the top of the 75. He worked in the Kennedy Space centre, designing experiments that would go to the moon. A seismometer which was there to detect moon quakes, and the other was a laser reflector which was used to bounce back laser beams sent from the earth, to measure the distance from the earth to the moon. Keith left another legacy. Two of the brackets that held the solar arrays on the seismic experiment were going to be thrown away on the moon, and oui to be thrown away on the moon, and our nasa principal engineer suggested that we sign the back of one of these brackets. I signed my name, and drew a little union flag, because we had actually had 27 british engineers working on the experiments. And my signature and the union flag is on one of these. The us flag has disintegrated. The ultraviolet light will have just ruined it and it will have just broken up. But hopefully our union flag drawing is still there. There he is putting his foot out. It is fantastic, i remember. Gene was gripped by the moon landing. It kicked off a fascination with space that now spans four generations of herfamily. Her that now spans four generations of her family. Her grandson dan that now spans four generations of herfamily. Her grandson dan runs an observatory in northumberland where the family have gathered. The moon is something you look at all your life, it is beautiful. But imagining people being on it, it is so hard to believe. Why are you interested in space . Because theres still lots to be discovered about it, and i love it because it is where our home is. The technology that they used was less sophisticated than the mobile phone that sat in your pocket, but it just makes phone that sat in your pocket, but itjust makes you really excited about now we have moved on so much asa about now we have moved on so much as a civilisation since then, in terms of technology. What can we achieve next, where can we go next . That was the thing on which those men were walking 50 years ago.
