The ongoing investigations into the Russian's meddling in the 2016 presidential election, led by both the special counsel and congressional investigators will very likely to stretch into 2018. But at the same time, the members of Congress are becoming increasingly divided over how much more time to spend on the probes. While House Republicans have expressed a desire to end up their investigation before Christmas, the ranking Democrat Rep. Adam Schiff of California informed ABC News that there are several witnesses who are yet to be interviewed and which would take a few more months. Schiff said that if we want to stick to a political timetable then the majority will bring this to an end, but it will be a tremendous disservice to the country. Schiff clearly mentioned that there are actually dozens of witnesses who have relevant testimony and thus it is going to take some time to be completed. He also said that the worst thing that he can think is that a report is to be made to the public that is incomplete and therefore misleading thereby having to explain why months from now which is what has been told to the public just was not true because we did not want to find the evidence.
There is a similar kind of rift among the members of the Senate Intelligence Committee, although very less had been said when their work would finish. Republican Sen. Richard Burr of North Carolina who is the chairman of the committee has mentioned that he is expecting to have the interviews wrapped up by the end of this year and to have a report before the primaries. This is what his staff had said. The Democrats have said privately that they are hoping that the work will continue until they have answers, even if more time is needed in doing that. In addition to that there is the matter of the Special Counsel investigation. The Special Counsel's office has still not given any indication of how long they expect their wide-ranging probe to continue though ABC News is aware of at least one witness who has been scheduled to meet with investigators in the month of February. The trial for former campaign manager of Donald Trump, Paul Manafort is currently scheduled for May 2018 and the regulations that govern the special counsel's office require Mueller to provide a status report & budget to the Attorney General in each fiscal year.
