Transcript for Washington, D.C. ramps up security, investigates new threats ahead of inauguration
Thank you, George. In the aftermath of the capitol siege authorities are fortifying our thaigs for the inauguration and investigating a wave of threats. Our chief justice correspondent Pierre Thomas joins us from Washington with more. Good morning, Pierre. Reporter: Michael, good morning. I can't recall any inauguration with this much tension as we head down the stretch. We have new information overnight that some of the National Guard protecting the capitol will be armed and there's new incredibly disturbing intelligence. There's one estimate of more than 10,000 angry trump supporters coming to the nation's capital, many of them armed. One scenario briefed to congress involved heavily armed radicals assaulting the capitol and potentially other locations like the white house. One reason authorities are worried is they have identified individuals talking about assassinating politicians including a Chicago area man who allegedly had been discussing killing leaders in Washington in order to block Biden's I know it sounds crazy and they're still vetting the credibility of some of the threats but after last week no one I'm talking to is willing to say it can't happen. As a result it's about to become fortress Washington and street close Sures have started. There will be additional barricades blocking streets including trucks and buses. The plan is to make it extremely difficult for large masses of people to gather and move quickly. Beyond the National Guard there will be thousands of police and special agents to include snipers on rooftops as the FBI and homeland security officials are also consulting with officials in all the nation's state capitals and authorities believe they can make it safe but there are so many people out there, so angry, and so many with guns, Michael. Thank you. Doesn't even sound like reality. Thank you, Pierre.
