Former presidential candidate and Vermont Sen. Bernie Sanders and Democratic National Committee chairman Tom Perez are kicking off a nationwide tour in Maine.
A rally is set for Monday evening at the State Theatre in Portland.
Sanders and Perez say they want to talk about growing a "stronger, grassroots" Democratic Party that can take on Republican President Donald Trump and win elections.
Sanders told the Associated Press this week that Trump would be a one-term president because of his support for policies like the GOP health care bill.
The tour includes visits to some tossup and Republican-leaning states where Democrats struggled in the last election. Sanders and Perez are slated for appearances next week in Kentucky, Florida, Texas, Nebraska, Utah, Arizona and Nevada.
