Reporter michelle miller, cbs news, birmingham, alabama. And thats the overnight news for this friday. For some of you the news continues. For others check back a little later for the morning news and of course cbs this morning. From the Broadcast Center in new york city, im anthony mason. Announcer this is the cbs overnight news. Welcome to the overnight news. Im jericka duncan. Dozens of tourists and journalists are thankful to be alive this morning after surviving a huge explosion at italys mount etna, europes most active volcano burst into life without warning, sending boiling steam into the air and rocks and lava raining down the mountainside. Heres seth doane. Reporter mount etna has been putting on an impressive show for days, spewing lava and steam, but no one expected this. The massive explosion was caught on camera by a bbc crew. Piping hot volcanic ash and rock rained down as tourists and the crew fled. One reporter described it as running down a mountain, being pelted by rocks, dodging burning boulders and boiling steam. Whoa. Reporter a camerawoman shook burning embers off her back. Get it off. Reporter she later tweeted a photo of the hole burned in her jacket. At least ten people were injured from flying debris, take shelter in a passing snowcat. The blast is whats known as a phreatomagmatic eruption caused by extremely hot lava hit much k0e8der snow. Police on snowmobiles responded for what was a lucky escape for everyone. There are always risks involved with getting close to an active volcano, but anthony, experts tell us this kind of explosion is a rare event. It takes a perfect storm of circumstances for it to happen. Its been a rough week for President Trump. His latest travel ban is now stuck in legal limbo. His Health Care Bill is already on life support. His budget plan is described as dead on arrival in the senate. And his allegation of being wiretapped by the former administration is being denied by congressional leaders in his own party. Major garrett reports. Reporter false. Thats what the Bipartisan SenateIntelligence Committee called President Trumps wiretap allegation. Based on the Information Available to us, we see no indications that trump tower was the subject of surveillance by any element of the United States government. House Speaker Paul Ryan reached the same conclusion. That no such wiretap existed. Reporter as did adam schiff, ranking democrat on the house Intelligence Committee. Thats just complete nonsense. Reporter White House PressSecretary Sean Spicer said the president s unproven allegation would be vindicated. He stands by it but reporter yet the president has asked for no evidence from the fbi or Intelligence Community and has not directed the Justice Department to provide any to congress. In his first Public Comments on the matter, President Trump told fox news his allegations stemmed from news reports. Ive been reading about things. I read in i think it was january 20th, a New York Times article where they were talking about wiretapping. Reporter the times did run a story that day headlined wiretapped data used in inquiry of trump aides. It did not report trump tower had been under surveillance. Mr. Trump then referred to something new and possibly classified. The cia i just want people to know, the cia was hacked and a lot of things taken. That was during the obama years. That was not during us. Reporter the president may have been referencing wikileaks disclosure of cia documents. Congressman schiff said the comment was concerning. But if this was an offhand comment by the president in the form of a dig at his predecessor, that is not how you want to declassify information. Theres more evidence of financial ties between former National Security adviser Michael Flynn and the kremlin. Flynn was fired after just a month on the job for lying about his contacts with a russian official while he was working for the trump campaign. Jeff pegues reports. Yeah, thats right, lock her up reporter just two months before retired Lieutenant GeneralMichael Flynn began advising the trump campaign, he traveled to moscow to attend a gala where he was seated right next to russian president vladimir putin. Today the top democrat on the House Oversight committee, elijah cummings, released checks, emails, and invoices that showed flynn was paid almost 34,000 to attend the event by r. T. , a Media Company the cia has said engaged in a kremlindirected campaign to undermine faith in the u. S. Government. It begs the question, why would President Trump allow him to be in his inner circle, receiving top secrets of our government . Reporter in a statement a Spokesman Says flynn, the former head of the Defense Intelligence agency, notified and briefed the d. I. A. Before his trip to russia and again upon his return. And that just wasnt acceptable to me. Reporter President Trump fired flynn after just 24 days as National Security adviser when it was revealed flynn lied to Vice President pence about conversations he had had with the Russian Ambassador to the u. S. And its not just his connections to russia that have raised questions. Just last week flynn retroactively registered with the Justice Department as an agent of a foreign government. He had a 600,000 lobbying contract with a company with ties to the turkish government. In addition, flynn received over 11,000 from a russian Cargo Airline and, anthony, was also paid 11,000 from kaspersky labs. Thats a wellknown Cybersecurity Company with ties to russian officials. City officials in dallas are scrambling to fix a deadly problem with the 911 system. It forces emergency calls to be put on hold. At least two people have died waiting for a 911 dispatcher to pick up the phone. One was a 6monthold boy. Omar villafranca. Has that story. Do you think 911 responding could have saved your sons life . I do. Reporter Bridget Allen left her son at home with a babysitter when the 6monthold fell and stopped breathing. The 40yearold baby zitter called 911 at 5 55 p. M. And again at 5 57 but was put on hold each time. This screen grab of the final call shows she was on hold with 911 for more than 30 minutes and never got through to a dispatcher. Really no apology, theres nothing they can say to heal the pain thats in my heart. That i have to bury my 6monthold son on monday. But you want an explanation. I want one. Its not acceptable that that happened, and weve got to make sure that it never happens again. Reporter dallas mayor Mike Rawlings said wednesday that hundreds of ghost calls have jammed the citys 911 system for months. These socalled ghost calls are made to 911 unintentionally by mobile devices on the Tmobile Network and are unknown to the caller. The calls then appear on a dispatchers screen as hangups. By law dispatchers have to call those numbers back, which bottlenecks the system. Tmobile executive david carrie says they first started to notice the problem last fall. We took some changes into the system that actually thought it had arrested the problem. Reporter but on saturday the city says it experienced a spike of more than 400 ghost calls. Tmobile sent a team of engineers to dallas to try to resolve the issue, and they clearasil rapid action begins working fast for clearly visible results in as little as 12 hours.
