Washington (CNN) A growing number of key Republicans are sending this message to the leaders of the congressional committees investigating potential Trump campaign collusion with the Russians: Wrap it up soon.
In the House and Senate, several Republicans who sit on key committees are starting to grumble that the investigations have spanned the better part of the past nine months, contending that the Democratic push to extend the investigation well into next year could amount to a fishing expedition.
The concerns are in line with ones raised by President Donald Trump, who has publicly and privately insisted he's the subject of a "witch hunt" on Capitol Hill and by special counsel Robert Mueller.
Democrats, meanwhile, are raising their own concerns that the congressional Russia probes are rushing witnesses -- including the testimony of President Donald Trump's son-in-law Jared Kushner -- as well as stalling appearances of other key Trump associates.
