Massive riot at a mexican prison. And is it really worth risking the zika infection. And plenty to keep you enteteained during thiz frozen valentines day weekend. Early today starts right now. Good to be with you. Millions of americans are bracing for dangerously cold temperatures this valentines day weekend. A polar vortex bringing bone chilling weather all the way down the florida. And whiteout conditions along sections of the new york thru way and in scranton nearby homes power lines all coated in ice. I cant even remember weve dropped this low in the northeast. So, i dont even know what that feels like. And youreot going to like it either. Really cold weekend across many spots. We are looking at some dampgngerous cold. This is the leading edge of the arctic air. 19 below for the wind chill in International Falls and normally that would stayy up in northern minnesota. It will sweep down the south and east and all the places under wind chill alerts. That means how it feels will drop to 35 below zero. Thats dangerous cold. You need to layer up. And it looks like areas of the southwest will be in the 80s this weekend. So, its not everywhere. Thank you very much. Next to politics as the two democratic predential candidates faced off in milwaukee last night. Kissinger. She talked about getting the approval or support or the mentoring of Henry Kissinger. Now, i find it rather amazing because i happen to believe that Henry Kissinger was one of the most destructive secretaries of state in the modern history of this country. I am proud to say that he is not my friend. I will not take advice from Henry Kissinger. I know journalists have asked who you do listen to on Foreign Policy and we have yet to know who it is. One of the biggest back and forth came when clinton jabbed sanders for not supporting president obama. Today senator sanders said president obama failed the president ial leadership test and this is not the first time that he has criticized president obama. In the past hes called him weak, a disappointment. The kind of criticism that weve heard from senator sanders about our president i expect from republicans, not from someone running for the democratic nominations to succeed him. Madam secretary, that is a low blow. Have work would president obama for the last seven years. But you know what last i heard we lived in a democratic society. Last i heard a United States senator had the right to disagree with a president , including a president w ws done such an extraordinary job. So, i have voiced criticisms, maybe you haven i have. Later, sanders hit back on critics saying only Clintons Campaign was historic and he was thwarting history. Well, you know from a historical point of view, somebody with my background, who has spent his entire life taking on the big money interests,s, think a sanders victory would be of some historical accomplishment as well. And the twitter discussion was a dead tie although sanders got more followers and clinton was able to narrow the gap from the start to the end. And now to the republican race and frontrunner, dondenald trump who is hiting all of the group. He took time to autograph a mohawk sporting baby and a bedazled trump pacifier p. For much of the day trump was in a heated back and forth with nemesis cruz after he said trump and rubio are with president obama on gay marriage. And he said cruz is a liar and eporter making some 252500 phone calls a day to topple donald trump here like he did in iowa. In the state of South Carolina, i dont think people are interested in someone, a republican candidate whos pushed partial birth abortion. Reporter cruzs strategy, paint trump as more liberal, with more ad said like this one on the way. He pretend to bee a republican. Reporter for his part, trump seems to be playing a more positive Political Campaign than before. Its going to be such an unbelievable reporter but in the more mannerly south, his colorful language may bowe a big turn off. Its crass. Its not how you want your president of the United States. You turn on the tv and you have a leading president ial candidate saying profanity from reporter marco rubio and jeb bush taking jabs that frontrunners and at each other. Jeb bush has no Foreign Policy experience, period. Reporter trying to prove South Carolina isnt simply a twoman fight. It was a dramatic end to a 41day armed siege at an oregon wildlife refuge. Four remaining wildlife activists surrendered after hours of tense negotiations. David frey had refused to come out but finally turned himself in. All expected to have an arraignment today. The refuge w wl remainn closed to the public for weeks. Meanwhile, the father of two activists taken into custody two weeks ago was also a aested after landing at the portland airport. He faces several felony charges four people remain hospitalized after a frightening attack at an ohio restaurant. That call about a man in a head scarf came in shortly after 6 00 p. M. Local time. He entered the nazareth h restaurant and reportedly began attacking people with a machete. Diners threw chairs and other objects to stop the attack. Minutes later, the suspect was stopped and police unsuccessfully tried to taser him and he then lunged at officers with a machete and a knife and he was fatally shot. As of now theyre not calling it terrorism. A prison battle between mexican Officials Say the fight started around midnight thursday between a faction of the infamous zedas gang and another group. Authorities say there was no gun fire. The situation is now under control and they have ruled out the possibility of a prison break. And the riot comes less than a week before pope francis is scheduled to viz at different prison. Now over 100 years later,r, we finally heard this. Thats what weve been looking for. Those are waves that came from a collision of two black holes, burst 20 times as big as the sun.

We will be inside, the reason why, this polar vortex, or a piece of it, will be heading our rection. High of only 9 in minneapolis. Well see the winds relax a bit, yesterday you heard them rattling.
