Mr president , are you a racist . It was behind closed doors in the oval office that donald trump allegedly claimed that immigrants from haiti, el salvador and african nations came from shithole countries. Donald trump said he used Strong Language during the meeting on immigration reform, with senators, though not that word. But he has been fiercely contradicted by a senior democrat who was present. I cannot believe that in the history of the white house and that oval office, any president has ever spoken the words that i personally heard our president speak yesterday. The no surprise, the president started tweeting this morning, denying that he used those words. It is not true. He said these hateful things and he said that repeatedly. From the united nation, in genveva, came the stiffest of rebukes. But on this continent, that word is an insult. Chant build the wall, build the wall. Build the wall was the cry of voters who loved Donald Trumps hardline stance on immigration during the election. We are going to build the wall, folks, dont worry. And he was said to be doing a victory lap at the white house last night, believing this row will rev up his base. Donald trump launched his campaign for the white house with an attack on mexican immigrants and rose to political prominence by claiming, falsely, that barack obama was not an american.

He said, one of our big focus areas for 2018 is making sure the time we all spend on facebook is time well spent. Facebooks founder admits users are being fed a heavy diet of news and adverts, together with the more personal posts from friends and family. In bristol today, many Young Facebook users agreed. Its quite clogged up with adverts for shopping and baby things at the moment, stuff i search on google. So i think it would be a lot better if it was just based around friends and family, without any adverts. Ijust feel like im being sold to the whole time. People are making assumptions about my opinions, my tastes, the things im interested in. Zuckerberg says, im changing the goal i give our product teams from focusing on helping you find relevant content, to helping you have more meaningful social interactions. This is the biggest change to facebook for many years. It follows controversy over the promotion of fake news, with fears the platform has been used by foreign powers to subvert democracy.

Families searching for missing relatives after the Manchester Arena bombing were subjected to intrusive media attention, according to a report. Its part of a review by Lord Kerslake into the response to the bombing in may last year in which 22 people were killed. Our north of england correspondent Judith Moritz has been speaking to one of the families affected. Within moments of the Manchester Arena explosion, the attack was worldwide news. Phone footage was shared immediately. Camera crews and journalists provided round the clock coverage for days afterwards. And there were countless posts on social media, as well. There was huge interest in the stories of those most closely affected. They included the family of martyn hett, one of those killed in the blast. Martyn had a large online following and had previously been on tv. His relatives quickly found themselves in the spotlight. Press reporters arrived at their house, before the family knew that martyn had died. We had people coming round, knocking on the door, ringing the bell, basically saying, sorry for your loss, but would you like to comment . He wasnt even officially dead yet. How can anybody be so cruel and say, sorry for your loss . We didnt find out officially until that evening that he was dead. The way the Emergency Services responded to the arena attack is already being reviewed by an independent panel. Now, it will also examine the role which the media played during the aftermath. Much of the media handled families in a very respectful way. But weve heard examples where that wasnt the case and we think that needs to be explored and understood. Walk on. The long struggle of those whose loved ones died at hillsborough has recently inspired a charter for families bereaved through public tragedy. There are elements of the response that could have been better. The arena review asks organisations to sign up to it and put the needs of such families before their own reputations. I want anybody who works in our Emergency Services to know that they will be supported in coming forward to tell it exactly as it was. Because that is what we need. We need the families to have the truth as quickly as possible. In march, the full review into the attack will be published.
