Donald Trump Jr. is scheduled to be in Maine in a few days, campaigning for his father at stops in Lewiston, Auburn and Gray, WCSH-TV reported early Monday.

He is the oldest child of Republican presidential nominee Donald Trump.

Efforts by the Portland Press Herald to reach the Trump campaign for the details and the exact timing of Trump Jr.’s visit were unsuccessful Sunday night.

The candidate has visited Maine four times during the campaign, most recently at a rally in Bangor on Oct. 15.

Trump’s son Eric, his third-oldest child, and his daughter-in-law Lara visited Maine on Oct. 6, when they toured an apple orchard in Turner with Gov. Paul LePage, who has been vocal in supporting the Republican candidate. They also made campaign stops in Auburn and Bangor.

Both Trump and Hillary Clinton have spent an unusual amount of time and resources campaigning in Maine this election season, especially in the more rural and northern 2nd Congressional District. While the Democratic nominee appears to have a lead in the 1st District, neck-and-neck polling in the 2nd District suggests that Trump could win one of Maine’s four Electoral College votes.
