Search and rescue crews found debris several hours later. Chip reid is in washington with new information. Good morning. Reporter good morning. Officials at Eglin Air Force base say searchers found some human remains and debris washed ashore from the black hawk helicopter carrying 11 servicemen but consider this a search and rescue mission and are continuing to look for survivors. Two black hawk helicopters flown from the Louisiana National guard were conducting a nighttime Training Mission carrying marines from a special Operations Unit based at camp lejeune in north carolina. One of the black hawks with four crewmen and seven marines went missing over water at about 8 30 eastern, 5 30 pacific last night. Weather may have been a factor in this accident. Since there was a dense fog advisory oubtt for areas of the Florida Panhandle last night. The second helicopter returned to base safely. It took several hours for serve and rescue teams to locate debris from the helicopters which washed ashore. The hunt is hampered by fog. Investigators may have to wait for the fog to lift before a more exhaustive search can be done. Chip, thanks. Hillary clinton insists she followed all rules when using private email for state department business, but the former secretary of state is facing new questions this morning after breaking her silence about the story. She told reporters yesterday that she deleted thousands of messages. Nancy cordes attended clintons news conference. Nancy, good morning. Reporter good morning, gayle. Well, democrats say theyre happy that clinton broke her silence after nine day, but republicans say they only have more questions, especially about those 30,000 emails she said she deleted in december. I opted for convenience to use my personal email account. Which was allowed by the state department. Reporter clinton told a crowd of hundreds of reporters she was simply trying to steamline when she decided to use a private email account as secretary of state. Looking back it would have been better for me to use two separate phones and two email accounts. Reporter but republicans want to know why it took clinton two years to give the state department her workrelated emails as guidelines require. She said part of the reason why she didnt obey the law was convenience. But i dont think convenience should Trump National security. It should like be houlnot, not and they wonder why she deleted half of her 60,000 emails in december. Clinton said its because they were personal. E emails about planning chelseas wedding as well as yoga routines family vacations. Reporter chairing the House Committee investigating the 2012 benghazi attacks. The bottom line is she was the sole arbiter whats a public and private record and you dont get to grade your own papers in our society, which is why i think we need a neutral detached arbiter to determine whats a Public Record and whats not. Reporter House Speaker john boehner said secretary clinton didnt hand over her emails ouch the goodness her of heart, she was forced to by effective oversight from congress. How could the public be assured when you deleted emails that were personal in nature that you didnt also delete emails that were professional but possibly unflattering . First of all, you would have to ask that question to every single federal employee because the way the system works, the federal employee the individual, whether they have one device two devices, three devices, how many addresses, they make the decision. Reporter gowdy admitted he doesnt have the authority to compel clinton to turn over her private server to an independent third party. She was asked twice whether she would do it voluntarily, and, charlie, she didnt answer the question directly but did say that it is a private server and its going to stay that way. Thank you nancy. Clinton spoke weeks before shes expected to announce another run for president. John heilemanns managing eder of Bloomberg Politics and author of a pair of books called game change and double down. Welcome. Happy to be here. Where does this leave Hillary Clinton . More questions and what are the questions . More questions and not put this behind her. Shes emboldened republicans now going to investigate her for months to come on not just on benghazi now apparently on these emails and i think even for a lot of democrats, there are still questions that are left unanswered. The questioned not good headlines. I opted for convenience is not something that you want to hear from a clinton. Because it reinforces bad narratives about her and i destroyed 31,000 emails no one will ever get to look at raises a lot of questions and uncomfortable even for democrats, not just republicans. What was the decision and who was ib involved in the decision and the criteria fo deleting . The question. Claims neg remotely related to government business, 30,000 of those emails she turned over to the state department. The other 30,000 she said were not related to government business at all and none of us have basis on which to judge that other than what shes saying to us trust me im Hillary Clinton. Im in this for the right reasons, again, its not i think for some people a satisfy argument that she is the sole arbiter of that. How does she get past it john . Can she . Shes obviously going to have a launch for a president ial campaign. A lot of energy forth, a lot of democrats love her. Still by and likely be cornerated as the democratic nominee nominee, but the question Going Forward for her is how does this play in the general election . Thats a much more diffuse but a lot of people in the country who look back on the 1990s and say, it was great era, pace prosperity liked bill clinton, but, boy, contentious period. The clintons constantly involved in melodrama, psycho drama. People are queasy about that and kind of weary of it. Theres been clinton fatigue, thats been a concept weve talked about a long time. This kind of thing revives it for her Going Forward. President s campaigns, successful ones are about the future. Yes. This essentially, sucked back into the past about a past controversy and hasnt even announced yet . Thats it. Exactly right, norah. You, frank rooney wrote about it in the New York Times. The picture yesterday a picture out of yesterday. Called to mind, were now having discussions again, incredibly about the Rose Law Firm billing records and whitewater what are the parallels to previous clinton scabbedals sal scandals and skewed oh scandals. Not what you want to have just launching a president ial campaign. Lovely to have you here. For the first time. So excited. Youre welcome back anytime. Okay. Be here tomorrow. All right.

This morning musicians robin thicke and Pharrell Williams owe the family of marvin gaye over 7 million. The federal jury found them guilty of ripping off a marvin gaye song when they wrote the 2013 hit blurred lines. How this decision could blur the future of the Music Industry. Reporter good morning. The attorneys for thicke and williams argued throughout the trial that while blurred lines may have had a similar feel to gayes song it was completely originalsthe jurys decision sent a message to musicians that sometimes inspiration can cross a line and become plagiarism. Marvin gayes children left court feeling vindicated by the verdict. This is a miracle. Reporter the jury agreed with the gaye familys claims ruling that the 2013 mega hit blurred lines which made more than 16 million infling and their fathers 1977 hit got to give it up. Reporter both artists admit they were inspired by gayes music but denied charges that they copied the song. Blurred lines is an independent creation from the heart and soul of Pharrell Williams and no one else. Reporter Pharrell Thicke and rapper t. I. Released a statement saying the ruling sets a horrible precedent for music and creativity Going Forward. Some in the Music Industry say the case could create a new standard when judging similar cases. The one and only part of a composition thats really protected by copyright is the melody of the song. I know you want it rear nowwere now able to look at lawsuits on the inspiration and feel of previous songs that could potentially open up the door for all kinds of different cases. Reporter the trial lasted more than a week both williams and thicke testified. Jurors never heard full versions of either song. Instead they were told to focus solely on the sheet music. Expert witnesses called musicologists compared the song note by note and came to different conclusions but gayes attorneys decided to focus on similarities in phrases. The hook youre a good girl reporter and the lyrics. This was about the copying of melody of harmony, it was about the copying of bass lines and keyboards. Thats what the jury found. Reporter and with that decision, some think the jurors hit the wrong note. I understand there are similarities but i also understand the notes are different and the songs are not the same, and you know no one own as genre. No one owns a groove. Reporter neither side is declares this case over. The attorney for thicke and williams says hes considering many legal option while the gaye familys lawyer will reportedly ask the court to block sales of blurred lines until a financial agreements been reach how to share any future money made from the song.
