probe, something they believe gave hillary clinton favorable treatment and led to her exoneration from any charges last year. this will be a big focus for republicans going forward in the new year, even as democrats say there's a lot more to investigate on the russia issue, many more witnesses to bring forward to their respective committees. the house committee, however, it looks like they may try to wrap up this investigation in the coming weeks. uncertain how long the senate intelligence committee will last. but the senate majority leader mitch mcconnell saying he's not going to step in, he's going to let the committee work itself out, so they can decide themselves on exactly when they want to wrap up their investigation. clearly a big focus on capitol hill when they come back into session in january, when this investigation wraps up and what they ultimately conclude. manu raju, cnn, washington. carrie card eero joins me n
