Chris Stirewalt talks about Democrat Party divide over impeachment

"Democrats had been helped by 'well, we're waiting for Mueller,'" he said. "Well, now that Mueller is here and we have the report ... as they speak to radicals, as they speak to those who say we have to impeach now, they don't have that same tool in their bag."

"For a long time Pelosi could say we're not going to do anything til after the report and then we'll make a judgment. Now the pressure's on. They're going to force them to make a decision, and that puts a majority of democrats in an uncomfortable position."
