. >> so, reena, did the president buy himself some political ka capital here by saying, i'm fightingor what i cam poindpa on, i made a fight for this and i'm not backing down. if he did not battle over this, the prospect of keeping his base, arguably his only support, could be zero? >> i think that would be giving donald trump a little too much credit. i think we're at a point really, essentially, where we should see the president for who he is, a man who lacks vision and strategy. this is an elementary schoolyard brawl, in my opinion. i think what's happening here is there's been a tug-of-war. obviously the wall is something he campaigned on and cares about so much that he continues to let it be front and center and realize that essentially his base is going to abandon him if he doesn't do something beyond the justices, right? so this wall is really it for him, and i think we're at a point where we just have to say that the president is putting the republican party, putting the country in a worse off place because of his lack of vision and strategy. this is not what great leaders ar

. >> let's bring in reena shaw, co-founder of the women's leadership always love talking with the threemocrats seem to be kind of tiptoeing around this whole idea of impeachment proceedin proceedings. they are shifting the focus to n nadler. are they still on the fence or you think they are waiting until they are sworn in to go full steam ahead. >> i think most people are waiting for mueller report. if you're a prudent politician, you can talk about all of this evidence that's accumulating. you can talk about the president being in as the late george h.w. bush said of another politician, deep doodoo. you can talk about all the smoke but you don't want to get to the remedies until more of the facts are on the table. that awaits this report. what is not happening is the witch hunt idea is a dog that won't hunt. this is just not working anymore for the republicans. the democrats now have a lot of running room to follow this investigation where ever it leads. >> okay. let's play for you what democratic senator chris murphy said today. take a listen to it. >> the president has now stepped in

reena, you got that article. i want to read more of it for you before we talk about it.e trump adviser who spoke in a position of anonymity said trump has been spooked not by the mentors but by a brutal rebellion on the righ right earlier this month when he talked about the border wall. they said, the president into this position in the stand off. is that the case? is that's what's keeping him from not budging? >> that's it. there aren't many things that scare this president but losing his base is really one of them. that's because he routinely plays to them. i've said this president is not much of a strategist. i've called him out on not knowing ha know ing what he doesn't know. i think he knows what he's doing and his long term strategy is to win the popularity contest that he thinks the presidency is and to win re-election. he doesn't care what happens to republicans in the house. he cares about his base re-electing him. he continues to feed them. i'm probably one of the very few republicans out there that wants to see speaker pelosi take the g g gavel later this week
