now, police tell me that osha, the occupational safety and health administration, is here the scene investigating, and we will stay on top of this developing story and bring you any updates as we get them. jim, doreen. >> all right. mee cho reporting. thank you, aimee. it is the testimony everyonn capitol hill is talking about, but tomorrow will democrats be able to extract anything from robele muel that he hasn't already said on paper? >> the justice department wants to make sure that mueller does not stray from his report onss run interference in the 2016 election. nbc's craig boswell joins us live from capitol hill with a preview of the hearings now just about 15 hours away. hi, craig. na reporter: hi, jim and doreen. now down to fil preparations as both sides get ready for tomorrow's highly anticipated testimony. former special counsel robert mueller stepped into this hearing room wednesday to be questioned for the first time about his russia report. the department of justice citing

executive privilege is warning mueller to stay within the boundaries of the report. >> it's part of the ongoing cover-up by the administration to keep information away from the american peoplert >> repo: the house judiciary committee will question mueller first followed by theou he intelligence commit. >> administration is making the broadest most claims executive privilege hi that i any president has ever made. it is a stonewalling and delay tactic. >> reporter: the former special counsel h previously promised he will not veer from his findings. >> any testimony from this office wouldnot go beyond our report. >> reporter: if that's mueller's intent, wt's the democrat strategy? >> get mueller to say in hiswn rds exactly what he found in the hopes that that will shift public opinion. >> reporter: according to the pew research center tw-thirds of americans and for the first time a majority of republicans believe mueller conducted a fair investigation into russian interference in the 2016 election. >> i've read his report. i accept thefi dings.

no collusion. now, we should note as the special counsel does that on collusis not a legal term. it was something that the counsel was not looking for. mueller did not establish a criminal conspiracy between the trump campaign and russia, but mcquaid and vance point to severalfnstances o possible interference, clupgs the trump tower meeting, sharing polling data andcommunications with wikileaks. they say that could be rollusion. now, myth numbe two. the other phrase that often follows the first. no obstruction. well, attorney general william barr came to that conclusion, but mueller did not. in his only public remarks mueller referenced department of justicepolicy thatrevents a sitting president from being criminally charged. his report also says, quote, while this report does not e concludthat the president committed a crime, it also does not exonerate him. myth number three, the argument thecause the president did not step in and end the mueller investigation there can be no n,

obstructiobut mcquaid and vance say the report found several instances o possible interference, including mr. trump asking white house counsel don mcga to fire mueller and asking former attorney general jeff sessions to un-recuse himself.ur myth number the president's claim that the case is closed and it's all about democrats tomorrow ing for a do-over, while the special counsel's report is complete, there's still multiple congressional probes under way that's not limited to the same narrow scope as mueller's investigation. the special counsel's office also made more than a dozen referrals to other department of justice offices. only a couple of which are public at th point. we'll see what happens tomorrow. jim, doreen, back over to you. >> we will indeed, leon harris, thank you. nbc news, of course, will provi special coverage of robert mueller's entire testimony starting at 8 sack in the morning. it's expected to continue into the afternoon. join us afterwards right here for "news 4 at 4:00.

corners of your report. look, this is sething that mueller already said he was going to adhere to back in may, but it's roiled democrats. they do have some key questions for mueller. mong them, would mueller charge president trump with a crime if he were not att sig president? why did the president never sit for an interview wither muell? why didn't mueller subpoena him, for example, and how receptive was the trump campaign to russia's help and this is ju a few questions from democrats. republicans said they are going to drill down on allegations that mueller and his team may have hadayn some w that's obviously a charge that you heard from president trump over and over again. something that has been dismissed frankly by the justice department, so i think that there are going to be moments in which we see some fireworks, but mueller's goal tomorrow is not to make any news. he's going to be testifying for five hours before two different

committees. we learned late tonight that one of his former top deputies is going to be sitting next to him in the hearing room. he won't benswering questions, but he will be there to help advise him. guys, back for you. >> washington and the world will be watching. nbc's kristen welker. kristen,hanks so much for joining us. >> thanks. >> and we'll look for more of your reporting just ahead at the top of the hour on "nbc nightly news" with lester holt. >> coverage of those hearings begins tomorrow morning at 8:00 a.m. a rare tornado touched down on cape cod earlier a today, you can see it left behind a mess for homeowners and businesses. the twister snapped trees and knocked out power. portio of a hotel roof were ripped right off. the last confirmed tornado to hit cape cod was october of last year, but, doug, cape cod tornadoes are even more rare than that, aren't they in. >> two in the last year or so, so the last one was last year i, augusnd then you go all the way back to 1977. >> whoa. >> that's how long it's been since they have had tornadoes,
