A protester interrupted the final debate between Republican Sen. Susan Collins and Democratic challenger Troy Jackson in Maine, setting off a brief exchange between the candidates. The source does not specify when the debate took place.

The demonstrator shouted concerns about artificial intelligence data centers, saying they were harming the climate and contaminating water. As security personnel escorted the protester from the debate hall, Collins said the person was one of Jackson’s supporters. Jackson responded, “Oh, shut up,” then said he did not know the protester.

The candidates later confronted each other during a question-and-answer portion. Jackson asked whether Collins looked down on him or on working-class people more broadly. Collins denied doing so and referred to her upbringing in Caribou and an early job picking potatoes.

Jackson has sought to connect Collins to President Donald Trump, arguing that she would support him whenever he needed her. Collins countered that she votes independently and described herself as the Senate’s most bipartisan member. She also said the Senate did not need more lawmakers who vote strictly along party lines.

The hour-long debate covered a range of topics, including the Iran war, immigration, fuel and electricity costs, federal deficits, Supreme Court reform, political spending, gun policy and climate change. The source does not provide detailed exchanges on each issue.

Collins is seeking a sixth term. Jackson, a former state Senate president and logger who grew up in rural northern Maine, won a special Democratic nominating convention in late July after the party’s primary winner, Graham Platner, ended his campaign. Platner withdrew after allegations that he raped a woman he had previously dated; he denied the allegations. The source says Jackson had campaigned alongside Platner during the primary and had earlier sought the Democratic gubernatorial nomination without success.

The report characterizes the Senate contest as highly competitive. It says recent public polls placed the candidates within the margin of error and that Fox News’ Power Rankings and three named nonpartisan handicappers rated the race a toss-up. No specific poll results or field dates are included in the supplied material.

Collins is the only Republican senator running for re-election in a state Trump lost in 2024, according to the source. It also notes that she defeated Democrat Sara Gideon by nearly nine points six years earlier, even as Joe Biden carried Maine by a similar margin. That history provides context for Collins’ record of surviving Democratic challenges, but does not establish the outcome of the current race.
