Uncertain impeachment schedule leaves 2020ers scrambling

WASHINGTON (AP) President Donald Trump’s impeachment trial in the Senate hasn’t yet begun, but it’s already complicating crunch-time campaigning for the five Democratic senators seeking the White House.

Sens. Elizabeth Warren of Massachusetts, Bernie Sanders of Vermont, Amy Klobuchar of Minnesota, Cory Booker of New Jersey and Michael Bennet of Colorado are facing the prospect of having to return to Washington this week if proceedings begin.

In the absence of a trial, the candidates will try to fill the time with hastily scheduled campaign events halfway across the country, in Iowa and elsewhere.

The leadoff Iowa caucuses are now just four weeks away.
