Reporter trump spent the week doing damage control, Holding Meetings with nervous Party Leaders and donors, trying to convince them he can stay on message and wage an effective general election campaign.

Reporter womens rights advocates delivered a strong message along with three boxes representing about a million signatures to the state commission on judicial performance. Theyre demanding the removal of judge aaron persky from the bench, saying he was far too easy on former stanford swim champturned sex offender brock turner. Stanford law professor Michele Dauber is leading the charge. O it shows how angry people are, that one Million People nationwide have signed a petition saying, you know, do something. Reporter turner sexually tsaulted an unconscious woman on campus last year. His three felony convictions could have put him in prison for 14 years. Prosecutors argued for six years, but judge persky only gave him six months. Legal analyst Laurie Levinson it just seems way too low for what we know now about what happened in this crime. Reporter but was it lawful . It was definitely a lawful sentence. Reporter even prosecutor Alaleh Kianerci says the judge followed the law and did not believe turners race or athletic standing played a role. He was absolutely neutral and fair during the trial. We just dont agree with the sentence. Reporter judge perskys sentence was partially based on a Probation Department recommendation that cited turners lack of criminal history and youthful age. But in a nowviral letter directed toward her assailant, the victim called it a mockery of the seriousness of his assault. The signatures gathered so far may be largely symbolic, because only Santa Clara County registered voters can authorize a recall. The other option, impeachment, hasnt happened in california since 1929. The protests are expected to continue tomorrow at stanfords graduation. Dena . Ninan carter evans in los angeles, thank you.

Its a sanctuary for endangered elephants that were abused in captivity some in circuses, others in thailands illegal logging industry. Lek chailert founded the park 20 years ago. With the help of volunteers, shes rescued and rehabilitated hundreds of elephants and given them a safe home. Chailerts affection for the herd and her ability to connect with these magnificent and gentle animals have made her known as thailands elephant whisperer. To see them, freedom, is beautiful. Teyre trumpeting, theyre singing a song, theyre talking. Many of them arrive here like a zombie. Some of them arrive here, they dont know they are elephants. They stand still, they talk by themselves, they walk in a circle. Some of them, when they arrive here and they see the other elephants and attack, or they attack people. When i talk to them, i treat them like my family. This is faa sai. We rescued her from the circus. When she first arrived here she had both legs on shackles, and you can see that her feet, because she was tied up for so long a time, her feet turned like this, and we can see that the chain cut, cut her deep in the leg. We understand even if we speak a different language, but we understand each other. We have to, first thing, heal them. We have to heal them with love. We have to let nature to rehab them. We have to make them feel that this is a safe place for them. Trust is the first thing that we have to go and do. When i stay under an elephant, i think i trust them more than when i walk on a sidewalk because they would never do any harm. If we dont change our attitude, we cant expect the next generation to learn and to stay peaceful with the other beings on this planet. When i first found an elephant, each of them blind, lame, you know, a handicap, its very sad. But when, one day, they start to roll in the mud, they start to enjoy trumpeting, swimming in the river, that is the day i have a tear because i have a tear of joy.
