Graham Platner's wife called reports that her husband had previously exchanged sexually explicit text messages with several women "shameful" over the weekend, the latest controversy to hit the Maine Democrat's whirlwind campaign.

Platner, an oyster farmer and combat veteran, posted a video taken by his wife, Amy Gertner, who reportedly told his campaign of the text messages last year. In the five minute video, Gertner avoided speaking directly about her husband's reported texts, dubbing the broader coverage as "gossip" and saying that "being married is hard."

"I find it really shameful that there's a group of media outlets and people who are willing to spread gossip," she said in the informal, selfie-style video where she walked along a road. "No marriage is perfect, and I don't want a perfect marriage. I want my marriage."
