0 museum and library itself every single year. today all of the pomp and circumstance, it officially opens to the public on may 1st, jon. >> have as you're speaking the first lady and the four other surviving first ladies are being introduced to the crowd. a round of applause there for them. casey stegall there at the opening of the bush library and presidential center, we will have more of the live festivities just ahead. thanks, casey. jenna: you wonder how much small talk takes place within the groups. jon: wouldn't you love to hear it. jenna: a little fly on the wall to see what the conversation -gs are like. we are going to continue on with a few of our other top stories today. there are new concerns the boston terror investigation may have hit a major snag. here is the picture that is slowly coming together for us. officials were apparently questioning the surviving suspect at the hospital where he was being treated, and that interrogation came to a screeching halt when a judge arrived and read him his miranda brother fox news is told that at the cia's request his name, two possible dates of birth and a varying of the name proceed jivedded to them by the russians were entered into a government database of known and suspected terrorists. this is called the tide database it's over 500,000 people and this seems like the big marketplace where names are drawn from the terror watch list and the no-fly list. this was the first step to making either of those lists but not enough of a step to have prevented him from leaving the country in 2012. >> before we health you go can we ask you one more quick question going back to the first point you were making. we've been reviewing some of the reporting over of the last 24 hours some of which coming from megyn kelly as well about happened inside the hospital room. do we know who sent the judge, who sent the magistrate to read the miranda rights? why, or who sent them at that time? >> reporter: you've hit on the key question. the issue this morning is whether this was directed by the justice department here in washington or it was selfdirected by the u.s. attorney's office in boston. but what is clear from the facts of our reporting is that this interrogation process was interrupted and i would add it was interrupted less than halfway through the public safety exception and i would add that in situations such as this based on my reporting on the underwear bombing in 2009 is when you have a suspect who has been either severely injured or heavily sedated that it's very slow going this these interrogations and often the interrogators have to go back several times to try to verify the information given the circumstances. jenna: a lot for us to consider there. catherine, thank you, we appreciate that very much. jon: that is very strange. all of a sudden in the middle of this interrogation the magistrate shows up with the miranda warnings. jenna: it's interesting to note that it could be a local call. you wonder who is in charge of the entire investigation and how some of those calls are made. jon: a case with national implications, and i don't know. somebody pulled the trigger on the judge, and the miranda warnings. we'll find out more i'm sure. we are also learning more about the bombs used in the boston terror attack. investigators now know what materials were used and how they were detonated. molly line is live in boston. tell us, what are we learning about the bombs, molly? >> reporter: well, jon we are learning from a joint intelligence bulletin sent out to local state and federal investigators a little more forensic analysis, essentially that the bombs were not actually identical and that they relied as catherine herridge mentioned a few moments ago on remote controlled car parts. the bullying goes ton to say that each device likely incorporated an electric speed controller used as a switch mechanism and rechargeable battery pack to the power source. the type of explosive is listed as a blend containing nitrate and hoop objection axidizers. this was consistent with fireworks. we have confirmed that the older brother tamerlan bought fireworks in new hampshire in eastbound if. jon: if the bombs are not the same what is the difference, are they telling it. >> reporter: it comes down to shrapnel. one of the bombs had be bbs and nails and the other bomb only had nails. that's why doctors at hospital seeing different patients were seeing different types of shrapnel. the answers those questions. right now the federal authorities have been in new bedford, massachusetts searching a landfill near to the ums dartmouth campus. that is where the the suspect dzhokhar tsarnaev attended schools. they could be looking for evidence as to purchases made in the days before the bombings, this is his trash or discarded belongings to the actual bombings. jon: that sound like a need el in a haystack. i guess if it's there they will find it. jenna: the jodi arias murder trial fascinating television viewers across the country. you won't believe what some people will do to get a seat inside that courtroom. we'll tell you coming up. plus, speaking of long lines, a lot of long lines amount the airports these days. apparently they may be the least of our correspond reese. our next guest says furloughing air traffic controllers is like removing stoplights and stop signs from our roads. is our safety at work?
