Feeling as though people were laying the blame on him. And those are tough questions with that this White House has been facing for a few days now and having to attempt to reconcile the president’s own rhetoric that we’ve heard from him on the campaign trail and over the last. Frankly you’re so plot and you’re so plus with this new call for unity which he just echoed. Right there in the in the White House east room but let me just show you would treat it just a few hours ago this morning. The president put out that’s raising some eyebrows Republicans are doing so well in early voting in at the poles and and now this new in quotations bomb stuff happens. And the momentum greatly slows news not talking politics. Very unfortunate what is going on Republicans. Go out and vote soap the president I’m comfortable with the coverage. Of this and prickly with those tough questions that have not let up wit you know initially the president turned this attack into an attack on the media heated softened his rhetoric in the hours. At or rather I should say these these bonds these packages. It’s her turn to tacked to turn this to. Blame the media for what he’s saying is is reserve is the media’s fault. The White House has pushed back strongly in drying any connection between the president’s tone and what we’re seeing around the country right now but certainly. These are not questions with that are going to go away for them particularly. As the rhetoric heats up in the middle of this mid term election. Absolutely Cecilia Vega the White House the president also applauding law enforcement talking about how quickly they were able. To apprehend a suspect let’s get right to Pierre Thomas or senior justice correspondent in Washington. Because we’re getting a much more information about the suspect Pierre. And some of that key element some of the things that led authorities to that person what do you tell us.

Again the case wrapped up by the FBI ATF Secret Service the suspect is being identified to us as a sees art site got 56 years old. Ivan tour of Florida law enforcement officials as you can see by some of the aerial shots we have have been investigating. A car perhaps associated with the suspect they’re questioning him trying to get additional information. Our law enforcement officials are breathing a sigh of relief they think they’ve made a major.

In in Virginia to be inspected. How does this move forward from here. What he’s willing these packages are these presidential devices are being sent to the FBI laboratory. In chronicle Virginia where they are being dissected. Taken apart piece by piece so there. They can analyze what exactly we’re talking about one of the things they want to determine is high by how viable. These devices are or are not. The other thing that I can tell you with that there are quite concerned about is that there could be additional packages still in the pipeline that have been shipped out already. And law enforcement officials. Are are still working this case hard. No resources being spares so this is still ongoing matter despite the break in the case are here Thomas forest thank you and I do want to point out while the president called them bombs we’re calling them suspected explosive devices. Because law enforcement sources are telling us they don’t know yet those sophistication level of these devices they want to inspect them and that’s all part of the investigation.
