Ken Jennings has apologized for problematic things he's said in the past on social media! As Entertainment Tonight shares, Jennings— who's known for being the longest-running champion of the game show Jeopardy!— took to Twitter on Wednesday to express his regret about the way he's conducted himself online.

Jennings sorry for "unartful and insensitive" tweets

Jennings made a thread of tweets acknowledging the issue, which began with an explanation of his actions. "Hey, I just wanted to own up to the fact that over the years on Twitter, I’ve definitely tweeted some unartful and insensitive things," he said. "Sometimes they worked as jokes in my head and I was dismayed to see how they read on screen."

"In the past, I’d usually leave bad tweets up just so they could be dunked on. At least that way they could lead to smart replies and even advocacy," Jennings continued. "Deleting them felt like whitewashing a mistake. But I think that practice may have given the impression I stand by every failed joke I’ve ever posted here. Not at all!"

Jennings is taking over as interim Jeopardy! host

Jennings has faced backlash on Twitter over the years for making jokes at the expense of others, including disabled people. "Nothing sadder than a hot person in a wheelchair," he tweeted back in 2014. As Entertainment Tonight mentions, Jennings supposedly deleted that particular tweet after the passing of longtime Jeopardy! host, Alex Trebek.

"Sometimes I said dumb things in a dumb way and I want to apologize to people who were (rightfully!) offended," he went on to say. "It wasn’t my intention to hurt anyone, but that doesn’t matter: I screwed up, and I’m truly sorry."

Jennings' social media apology comes after he was recently named the first guest host of Jeopardy!, taking over from Trebek in the interim. "If 2020 has taught us anything, it’s that we should be kinder to one another," he concluded. "I look forward to heading into 2021 with that in mind."
