Now, the snow is predicted to stop tonight, but the biggest problem is tonight after it stops, another round of freezing could happen which means all of this could turn into ice. And, gayle, in addition to all of the grand transportation issues there will be some air transportation issues. About 50 flights in philadelphia are canceled at this point. Stay warm. Thats good to know if youre heading there. Charlie says stay warm vinita. We second that. Thanks a lot. Heres a look at the driving conditions just outside philadelphia.

Norah, back to you. They dont need any more snow in boston but theyre probably saying, why not lets go for the record. Lonnie thank you. This morning Hillary Clinton is trying to get around the controversy other the email she used. Last night she tweeted i want the public to see my emails. I asked the state to release them. Nancy, good morning. Good morning. Now theyre actually issuing subpoenas for those emails. What prompted the move was not only did clinton exclusively use private emails when she was secretary of state but she housed them on a private server set up in her home in chappaqua new york. The republicanled House Committee looking into the benghazi attacks issued subpoenas for all Communications Related to libya. They also sent letters to internet firms to protect them relevant to her old email address. Hdr22 clintonemail. Com. It gave her the ability to retain what she wanted and remove the rest. With a private server you have full autonomy. If you want something deleted, it is clearly deleted on that server. She issued over 55,000 pages of private email in december and in midfebruary 300 emails were passed on to the benghazi committee. But that doesnt satisfy trey gowdy. I have no way of knowing whether she provided everything to the state department and i frankly have no way of knowing if the state department has provided everything to us. White House Press Secretary josh earnest was asking if clinton violated the rules. I also want to be Crystal Clear about the fact that this is a responsibility they assumed. Clinton was not required by law to use a government email but democrats still worry that this is going to give republicans more ammunition against her if she runs for president. And increasingly they fear that if she is the only major democratic candidate, that shes going have a huge target on her back, gayle. All right. Thank you, nancy. Testimony continues this morning in day 2 of the Boston Marathon bombing trial. Jurors viewed video yesterday including this video where the bombs exploded near the races finish line. You see the second blast down the street. Jurors also saw Surveillance Video from inside a Sporting Goods store. Employees grabbed clothing off the racks to make tourniquets if the wounded. Victim Rebecca Gregory wrote this on facebook after seeing accused bomber Dzhokhar Tsarnaev in court. Today i looked at you right in the face and i realized i wasnt afraid anymore and today i realized that sitting across from you was somehow the crazy kind of step forward i needed all along. Cbs news legal analyst rikky klieman, good morning. Good morning. You have the prosecutor showing the blast from another angle, you have the defense attorney saying it was him. Powerful language. Powerful language, by the way, on both sides. Opening statements are the most important part of a trial, id say. There have been studies that say that 80 of jurors minds are made up at the end of Opening Statements. Now, what you have here is you have the defense, it was him. So theres no issue about whether or not he committed these crimes. So the prosecutor could just accept that, but the prosecutor wont and shouldnt. What you have in this prosecutor is he paints a gory scene of gory. He payments a young man who really wanted to do the most murder and mayhem that he possibly could, who stands for four minutes by children and knows what hes going to do a radicalized muslim who wanted to take out revennt and someone who believes this is the first step to paradise. The prosecutors picture gets finalized by the horrendously calm acts of Dzhokhar Tsarnaev afterward, walking away we see in the video, going to buy a quart of milk or a gallon of milk in a whole foods. The following day tweeting out im a stressfree kind of guy. So what is a defense lawyer to do in the opening . Brilliant, judy clark. She was there saying it was him. He has a guiltynot guilty plea but admits it was him. Its a legal formality. Obviously judy clark would have liked to have him plead guilty and have life imprisonment. That wasnt in the offering. What you have here is judy clark who ive known for 30 years, one of the great lawyers, her whole idea is trust me im the arbiter of trust. Im the person telling you he did it im the person telling you why. Rikky klieman, thank you. This morning iraqi forces are trying to push into the suburbs of tikrit. Its the fourth day theyre trying to retake the city from isis. Holly williams is there in kirkuk. Good morning. Reporter good morning. The front line here in Kirkuk Province is the closest we can get to the battles of tikrit. We can see the black flags of isis 30 yards in that direction and beyond that in isis territory is iraqs main northsouth highway. Iraqi forces need to recapture that road if theyre going to defeat the extremists. A new isis video claims to show the militants fighting off the assault on tikrit. But on the citys outskirts, iraqi forces are still trying to encircle the extremists cutting off their supply routes. Saddam husseins hometown is a pocket of them since the invasion of iraq. Since then tikrit has been an isis stronghold. Fighting alongside the iraqi soldiers are troops from neighboring iran and iranian commanders are reportedly leading at least part of the operation. They realize their close allies are threatened, and i think that they would rather deal with isis here than they would on the gates of iran. Reporter retired colonel harry chuet took part in the invasion and told us the battles could turn the tide concerning isis. It now controls a third of iraq. Its a test to see if Iraqi Security forces are up to going after a major urban area. And perhaps taking mosul, iraqs second biggest city. Exactly.
