kimberly halkett is with us.is going to need all of the prayers he can get, because what he faces the challenge of how to be -- how to present a more united lower house of the congress, right? and face that dead lock which has plagued congress over the last year or so. >> reporter: sami you are absolutely right. we have to remember the reason there is even this nomination election process is because there is a group of republicans that are sort of further right known as the freedom caucus that forced out the previous speaker that you saw paul ryan acknowledging there, speaker john boehner. so he is going to have to work to try to bring those republicans that don't necessarily see eye-to-eye with members within their own party. he is going to have to try to unite them as well as the democrats in order to try to get things done. and you heard him acknowledging there that even he believes that it may take a little bit of prayer in order to try to fix what he calls a process -- he calls -- a day or two ago he said th

kimberly halkett, al jazeera. >> some support for hillary clinton. president obama down played her idea. >> she made a mistake, she acknowledges it. the way it's been ginned up has because of politics. maybe she could have handled the original decision better and the disclosures more quickly. this is one of those issues that i think is legitimate. but the fact that for the last three months this is all that's been spoken about is an indication that we're in presidential political season. >> the president said he learned about the e-mail server after clinton left office. >>> a former congressional staffer who investigated the benghazi attack said he was fired for trying to be objective. he says he works for house select committee oning benghazi for ten months. he said he was fired when he refused to focus only on hillary clinton's role in the incident. he said the secretary of state was clearly the target of the investigation. >> i'm trying to be orvet about the incident, hillary clinton does have a lot of explaining to do. we didn't need to deexcis d

. >> kimberly halkett is live for us in washington, d.c. so how significant is this change?is is a big change simply because not only are -- do we now have a new leader in the house of representatives, a saying power pull. this is third in presidential succession right after the vice president. but also because there seems to be a feeling in congress that this is a new chapter, if you will, this is an opportunity to as paul ryan said turn the page on some of the legislative gridlock that really has paralyzed washington in recent years. resulting in very little being accomplished to really historic proportions it's been called the do-nothing congress. simply because the two sides, namely democrats and republicans, are not seeing any common ground. paul ryan in his speech asked for prayers because he realizes a big job is ahead. as he tries to get not just democrats and republicans talking but also as you pointed out there, members of his own party who pushed out the former speaker, some of the further right republicans, who have been very strident in some of their did hdemand

. >> kimberly halkett is live for us in washington, d.c.t is the significance of this appointment? >> reporter: well, it is not actually an appointment, this is a nomination. he was elected by members of the republican party predominantly. this is a very powerful position in terms of presidential succession, third in line to the white house right after the vice president. so this comes as a big responsibility, and the fact that we have this election that took place is because the former speaker was forced out by members of his own party. the so-called freedom caucus. it will be now the new speakers job to try to not only work with democrats and reach across the aisle, but also members of his own party. it's an enormous task at hand simply because it wasn't achievable in recent years. there was legislative gridlock if you will. paul ryan is a big ideas guy. he says he has the vision to try to restore what he sees a legislative dysfunction and a failure to serve the american people. >> given all of that, what does it mean for president obama?
