Transcript for Senators running for president face a challenge with time-consuming impeachment trial
As the impeachment process moves forward in Washington, several 2020 Democrats may have to abandon the campaign trail for a senate trial. Here's Rachel Scott. Reporter: In this critical stretch of the primary, the Iowa caucuses less than two months away. An all-consuming impeachment trial could not come at a worse time for the five senators still in the race. Now bracing to split their time between the capitol and the trail. I have a great husband, a great daughter who will be out there campaigning for me. I'm gonna do my job. And of course it's going to present challenges with the campaign, but that's my priority.

Reporter: There's a strong jobs report that came out last week. I see it but I don't see it around here. Rachel, you have been in Iowa all week, tracking the candidates. This is the last weekend before the qualifying deadline for the next debate. Now just days away. Reporter: Exactly, and it comes as the field narrows. This could be the smallest debate stage we've seen yet. We've already seen three candidates drop out this week. 15 are still in, but only 6 so far have qualified for the next debate. Rachel, thank you. We'll have complete coverage of tomorrow's impeachment hearings. Streaming on ABC news live at 8:30 A.M., and on ABC starting
