Senator Susan Collins and Democratic challenger Troy Jackson clashed in their third debate of the Maine Senate race.
The two candidates disagreed sharply over the war in Iran during the Thursday night event.
Jackson criticized Collins for supporting military action without a clear strategy or congressional approval.
Collins defended her record, saying she backs tough measures when national security is at stake.
President Trump became another flashpoint, with Jackson tying Collins to the administration’s policies.
Collins pushed back, highlighting her independent votes and willingness to break with her party.
The debate grew personal at times, with both candidates questioning each other’s honesty and motives.
The race remains one of the most closely watched Senate contests in the country.
Four debates were scheduled, and the final one will take place next week.
Maine voters will decide the winner in November.
