Maine Democrat Senate nominee Graham Platner on Wednesday brushed aside questions about his past as he prepares to challenge Sen. Susan Collins, R-Maine, in November.

"There's nothing out there that's actually concerning," Platner said on MS NOW's "Morning Joe."

"People will make everything seem very concerning, because that's what people do in politics," he continued. "What I find to be kind of most curious is this is what everyone wants to make the campaign about, so we do not talk about the struggles of working Mainers."

Platner, an Army veteran and oyster farmer, has faced scrutiny over a tattoo he later covered after saying he did not realize it resembled a Nazi insignia.

He also apologized for now-deleted Reddit posts about sexual assault and Black people, attributing the comments to struggles with post-traumatic stress disorder after military deployments.

Although those issues surfaced months before Tuesday's Democrat primary, Platner has come under renewed scrutiny following reports involving a sexting scandal and allegations from former romantic partners.

The New York Times reported last week that three women who were romantically involved with Platner described his behavior as "toxic" and "unsettling." 

Platner has denied allegations that he physically intimidated or engaged in physical altercations with former girlfriends.

"Morning Joe" host Mika Brzezinski pressed Platner about whether voters could trust him to pursue issues involving alleged abuse against women, including efforts to release files related to convicted sex offender Jeffrey Epstein.

"Yes, of course, I mean, I engaged in consensual romantic activities with adults at an earlier part of my life," Platner said. "That seems like a fairly normal thing most people do.

"Going to an island with billionaires to possibly assault children is a vastly, vastly different thing," he added, referring to Little Saint James, the private island previously owned by Epstein, who died in 2019.

Sen. Bernie Sanders, I-Vt., has backed Platner and appeared alongside him at campaign events in Maine. Democrat leaders in Washington, however, have shown less enthusiasm for the nominee.

Senate Majority PAC, the super PAC aligned with Senate Democrat leadership, congratulated Platner following his primary victory.

"The difference between the two couldn't be plainer: Platner's agenda supports working people and families, while Collins upholds Washington's status quo," spokesperson Lauren French said in a statement on Tuesday.

President Donald Trump weighed in on Platner's candidacy during remarks to reporters at a bill-signing ceremony in the Oval Office on Wednesday.

"I watched that thug that's up in Maine. He's a thug," Trump said. "He's worse than any human being that's ever run for office, probably."

The president later added that he "made a lot of money picking out phonies."

"He's a real phony," Trump said. "He's bad. He's a bad person."
