0 snowden flat out denying he's a russian spy. he tells a reporter he ended up in moscow because that's where the state department wanted him. also right now, louis vuitton shoes, ipods, and a rolex watch. all on the list of illegal gifts that bob mcdonnell allegedly accepted. but is the case against the former virginia governor a slam dunk? -- captions by vitac -- www.vitac.com . hello, i'm wolf blitzer reporting from washington. all of that coming up. but right now, disturbing reports of shots being fired on the campus of the university of oklahoma in norman. campus and local police are responding, we're told. we don't know whether anyone has been wounded. the university is advising all students and faculty -- in fact, everyone on the campus, to shelter in place. unfortunately, this is an all-too-recurring situation. yesterday at purdue university, we saw a similar shelter in place warning being released after shots were fired there. this one at the university of oklahoma in norman, oklahoma. you're looking at live pictures courtesy of our affiliate, koco. once we get more information, we'll update you. but right now everyone on the campus is being told to, quote, shelter in place. let's go where tens of millions of people are struggling to dig out from the biggest snowstorm of the season. this powerful arctic blast is affecting multiple states and major cities, including washington, d.c., philadelphia, boston and new york city. schools and businesses are closed, and there are thousands of stranded travelers on the roads and in the airports. adding to all this misery, bone-chilling temperatures. chad myers is in massachusetts, margaret conley over at laguardia airport in new york. let's start with chad in plymouth, massachusetts. that's a town -- i take it a lot of snow, buried in snow, is that fair? how bad is it, chad? >> reporter: i think it's as bad as everything i ever saw in williamsport or up into buffalo where i live. sometimes lake-effect snow. now i believe we're getting ocean enhanced snowfall. i haven't gone over this hill yet. so this my end up on youtube. this is how much snow we have. easily 3 feet of snow here. and this is obviously part of some that was plowed, but when it gets plowed, you can see it's drifted. and again, one drift after another, as the winds blow 30, 35, 40 miles per hour, all day long today. and on the radar, we're seeing an enhanced area of snow from barns tabl all the way up here to plymouth. and that snow is going to be there for a long time. we could pick up another 6 inches of snow, especially south of here, and all the way down toward barnstable and is the south shore. keep watching. i have seven layers of things on here. they say dress in layer. i did. i tried it. i have five shirts on, two wind breakers on and with this wind at 15 below zero, wind chill factor, i'm still cold. i can only be out here 10 or 15 minutes minutes before everything starts to shut down. my fingers cold, nose cold, my mouth starts to not work. and obviously toes cold too. if you're outside or seeing someone outside, try to at least understand that they don't want to be outside for long, like dock workers or your flight attendants outside or the guys trying to load your bags on the plane. kind of give them a break today. it's cold out here. >> yeah, certainly is. any relief in sight from the brutal cold, chad? >> reporter: no, i don't think so. i don't see it. we have this ridge in the west and it has broken records in san francisco and l.a. for days now. maybe weeks. that ridge is making all the heat out west, but what goes up must come down. that jet stream is diving all the way down to georgia, and allowing all of this cold air to come straight down into the northeast, and i don't see an end to that for 14 days. and you know, less than 14 days from now, there's a super bowl not that far from here. >> yeah, in new jersey. northern new jersey. outside of new york city. all right, thanks, chad. we'll get back to you. go inside, warm up. the weather causing major problems for travelers, not just in the northeast, but the spillovers as far as air travel is concerned, significant. roads, meanwhile, packed with snow and ice, making for some very anxious driving. and if you're trying to fly once again, expect delays and cancellations. margaret conley is over at laguardia airport in new york city. what's it like there today, margaret? >> reporter: wolf, there are more cancellations at laguardia this morning than yesterday morning at this time. but the good news is that operations are expected to resume back to normal by this afternoon. there are about 4,000 flights that take off from this region every day. 20% of them have been cancelled today. but that is better than yesterday. you can see a lot of people behind me, checking in. a lot more activity here. yesterday at around 5:00, there were no flights taking off around here at all. and all of the airlines are handling this situation differently. delta, for example, they have cut down significantly on air traffic from jfk and laguardia. united, they have cut down on short haul flights. so the reminder from the airlines and from tsa is to check with your airlines before you come to the airport. the airlines are also saying, check online versus social media or calling in, because that's going to be a lot faster. wolf? >> certainly will. thanks very much, margaret. we'll get back to you. other news we're following, the 2014 sochi winter olympic games only just about two weeks away. russian security supervise forces are on high alert right now. they're responding to multiple threats from different people, and different groups. but as the former new york city mayor, rudy guiliani says, the threats aren't just because of lasting political unrest in russia. >> the minute you hold the olympics in a place, whether it's salt lake city or rio de janeiro or it's london, you have actually brought all the world problems to you. so, yes, sochi is dangerous, because it's close to the cow caulks. but every one of these causes gets attracted to you and you've got to have enormous security. >> joining us now our pentagon correspondent, barbara starr. we're learning a terror threat e-mail was sent to the olympic committees of hungary, and germany. are they being taken seriously? >> reporter: we're told that the officials say no, not for this particular threat. they don't think it's a genuine threat. they think it's some sort of random e-mail from the public. but that really has not eased concerns and worries, as you know, about the sochi olympics. security officials in russia are said to be looking for several suspects, so-called black widows, women that are -- will be claiming to carry out terrorist attacks, they believe, as part of the islamicin insurgent groups, fundamentalist groups in this region of russia. they're also looking for several men. so while this latest e-mail threat may not be of as much concern, it certainly has done nothing to ease overall worries about the games. wolf? >> as you know, the president -- president obama called vladimir putin yesterday to discuss a whole bunch of subjects, but also olympic security. what specifically is the u.s. offering russia as far as security help? >> well, this is fascinating. and unprecedented as far as anybody can see. what the two sides -- two militaries are now talking about, is ied bomb detection equipment, the same kind of bomb detection equipment the u.s. military has used against those roadside bombs in iraq and afghanistan. top military officials have met with russian military officials to say, look, we have some technology, you have some technology, can we get together and share for the olympics. looking now at the specifics of whether u.s. equipment, military equipment, would be compatible if the russians do ahead and ask for it to be sent to sochi. and, of course, the russians would have to ask. it then raises the question of whether a small number of u.s. troops would have to go along to operate the equipment. and then you get into the politics, because, of course, the russians are very proud, very much in charge of the security of the games. and it's not at all clear how much political authorities in russia are willing to ask for u.s. help. wolf? >> barbara starr at the pentagon, thanks very much. a very disturbing situation unfolding there. athletes and their families won't arrive, by the way, in sochi for several days yet. but american speed skater, it tucker fredricks, has already asked his family to stay home. he's worried about their security if they were to go to sochi. our own nick paton walsh is on the ground right now, joining us on the phone. take us a little inside. what's it like? what are you seeing as far as security preparations on the ground, nick? >> reporter: it's quite remarkable, actually. i've been to this town before when it was embracing itself the way it is. quite a difference when i got off the plane this afternoon. a number of people in track suits there to greet those arriving for the olympics. but as you drive in towards the town, you notice the fact that some streets are emptied. there seem to be the occasional core don put up. it's still early days so all of the various dragnets and core donees in place. you do see eventually the olympic area. that is pretty extensively cordoned off. i tried to get my accreditation to go in today, but the computer system was down, therefore they weren't able to dish out badges to a whole number of people. this was the third attempt to try to get the accreditation badge. in terms of the visibility security on the streets, it's not palpably leaking out at this point. i did today see a shift change of dozens of russian police marching in one particular direction. a lot of fences and areas where people simply can't go. you don't get that sense like you do, for example, in chechnya or the neighboring republic where there used to be check points every half mile or so. what's remarkable, wolf, it's a simple decision to hold an event like this in an area like this. i've been coming here ten years. this is a place where violence, bombings, shootings, assassinations, have become routine, frankly. and no matter what the russian federal government has tried to do to suppress it, they have become routine. so the decision to try and bring a game like this, a light on something russia has been trying to keep under a carpet for quite a period of time. but vladimir putin came to power separating, and now 14 years, and him being the leading figure inside russia, this enormous international show, and frankly one of his favorite parts of the country. and it's exactly those separatists he originally fought. now hardened into radical islami islamist extremists who might embarrass him, wolf. >> i know tens of thousands of folks are trying it to get to sochi to see some of these winter olympic games. is there room in that so-called security bubble that they have created around sochi for everyone to be protected? >> reporter: i think it's fair to say -- unless you have a ticket to come and see part of the games, then you probably are unlikely to come down here, given the noise about security threats. those people able to get inside that major cordon, a lot kept out, a lot of residents of sochi or perhaps who come down to assist with the games or people who are simply trying to soak up the atmosphere. i've got to be honest with you, at this point there is not much of a sense of fun or festivity. this is a town bracing for something it's not quite sure what is going to come next. i think the more jubilation will get under way when the area is flooded with vips. right now it's muted, extraordinary preparation, last-minute painting. in fact, one remarkable thing -- homes being covered up by a very regimented, very routine -- a fence erected along the main roads here. almost like a shield to the real russia for visitors. it's going to be fascinating for what this means to the putin administration if nothing goes wrong and there are a lot of people here deeply nervous, simply because of where we are in the world. a region racked by turmoil for well over two decades. >> let's hope it stays quiet. good luck over there, nick paton walsh already in sochi on the ground for us covering these winter olympic games. a silver rolex, two dresses and designer shoes. the governor of virginia and his wife accused of accepting $140,000 in illegal gifts. we have details of the indictment when we come back.
