The oldest son of Republican presidential nominee Donald Trump will stump for his father in Maine on Tuesday, with stops planned at a gun shop and indoor shooting range as well as a popular hot dog stand.

Donald Trump Jr., the child of Trump’s first marriage, will visit supporters at Howell’s Indoor Range and Gun Shop in Gray at 9:45 a.m. before heading to the Androscoggin County Republican Party headquarters in Auburn, which serves as the headquarters for the Trump campaign in Maine as well.

For lunch, Trump will stop by Simones’ Hot Dog Stand in Lewiston – a week after former U.S. Sen. George Mitchell, D-Maine, was there stumping for Hillary Clinton.

The visit to the gun shop is likely meant to shore up support for the Republican with Second Amendment voters and others opposed to tighter gun regulations supported by Clinton.

Trump’s campaign has focused on Maine’s 2nd District, where the Republican has had a slight edge in the polls over Clinton. Lewiston is the district’s largest city and it has twice selected Republican Gov. Paul LePage, a Trump supporter, over his Democratic and independent rivals.

The visit by Donald Trump Jr. is the sixth to the state by either the candidate, who has visited four times, or one of his offspring. Earlier in October Trump’s third-oldest son, Eric, and his wife, Lara, visited a Turner apple orchard, the Auburn headquarters and Bangor.

Meanwhile, Trump himself visited Bangor in person, attending a rally at the Cross Insurance Center on Oct. 15.
