reporter: chris whipple, an expert on white house chiefs of staff gives klain high marks. i think if you asked all the former living white house chiefs of staff, and i have, about ron klain, they will tell you no one has ever been more qualified for the position. sf reporter: and for now biden isn t eyeing a staff shakeup. are you satisfied with your team at the white house, sir? i m satisfied with the team. reporter: so there s no staff shake-up on the horizon but there is a change in some strategies the white house is employing, specifically passing the build back better plan the president has talked about breaking that up into chunks. and ron klain himself is talking about a change in strategy, talking less publicly about individual meetings, that was a lesson learned from some issues that happened with jesenator jo manchin. and president biden himself says
you call him. reporter: that hands on approach earned kato kaelin credit but also shared blame as biden s legislative agenda has stalled. i think he would say when you re the chief of staff you get some of the credit, maybe way too much at times, you get all of them and that s part of the deal. reporter: the blame game intensified last month after manchin said he couldn t back the president s build back better plan, pinning the blow up on the staff. they drove some things and put some things out that were absolutely inexcusable. why was he so personally insulted by what happened before christmas break? well, you ll have to ask senator manchin that. we worked very well with senator manchin. reporter: as sinking poll numbers drive finger pointing, kato kaelin has found himself in the cross hairs. one prominent democrat who speaks regularly with biden telling cnn if i was down this much in my ratings i d have to new chief of staff.
