Now george pop papadopoulos is at the red, hot center of the russia investigation, and tonight, a new report as to how he first came onto the fbis radar. Heres abcs david wright. Reporter tonight, new reporting about how us authorities may have first learned about russias attempts to meddle in the 2016 election. Reportedly because of what a former Trump Campaign adviser to this london wine bar in may of 2016. According to the new york times, trump adviser George Papadopoulos boasted to australias ambassador to the uk Alexander Downer that russia had political dirt on hillary clinton. The australians eventually passed that tip on to u. S. Authorities. According to the paper, that was reportedly two months later, about the time that hacked dnc emails started appearing online. Papadopoulos, who recently pled guilty to lying to the fbi, was part of the Trump Campaigns National Security and Foreign Policy team seen here at a meeting with candidate trump. The president posted a picture of that meeting at the time. But later, disavowed it. I dont remember much about that meeting. It was a very unimportant meeting. Reporter as for papadopoulos, trump ins level volunteer named george, who has already proven to be a liar.

And he never took an initiative without the blessing of the campaign. Reporter tonight, the president s lawyer declined to comment to abc news about the times story, out of respect for the special counsel and his process. David wright joins us now from florida. Part of the significance of the story in the times, it may clear up what exactly sparked this russia investigation. If its true. Reporter exactly so, dan. Assuming this story checks out, that means that back in july of 2016, the fbi started its investigation, not as a result of the socalled dossier comp e compiled by a former british spy and russian sources, and paid for by democrats, but rather foreign ally.

Reporter after more than a year and a half of painstakingly trying to figure out who brutally murdered natliya shal on mothers day, 2016, tonight, a suspect is finally behind controversial type of dna testing. This is pretty rare. Reporter police say the killers dna was found at shals home in baytown texas where she was stabbed to death but there was no match in the database. So, investigators tried familial testing, which searches for dna markers genetically similar to other violent offenders. It led them to an inmate whose brother then became the prime suspect. Our detectives were able to identify a person of interest in the case as 29yearold Byron Collins of baytown. Reporter police say then using dna from a discarded cigarette, they were able to link collins directly to the crime scene. You are charged with capital murder. Reporter familial dna testing is only used in several states and some call the method an invasion of privacy.
