Republican Mark Green's Resignation From the House Is a Little Mysterious
"I will look back fondly on my years of serving as your voice in Washington."

Republican margins in the House of Representatives just shrank a little bit more following news that Tennessee Republican Mark Green was resigning from his seat and leaving the chamber before the midterm elections. Following the news that Green was leaving his job early, many naturally wondered what he might be doing instead.
Green has not gotten into many specifics about why he's leaving the job early, and many naturally want to know what was urgent enough to take him away from a pretty important job. Here's what we know:

Why did Mark Green resign from Congress?
Green announced in early July that he would resign from Congress to start his own business. His resignation was effective July 20.
“To my constituents across Tennessee’s 7th District—thank you. The trust you put in me is humbling. I will look back fondly on my years of serving as your voice in Washington,” he wrote on X in a post announcing that he was stepping away.
“While I cannot give the details here, I will be doing something specifically designed to help America compete against the CCP [Chinese Communist Party], but this time in business,” he explained.
For now, then, the exact reasons for Green's departure will remain a mystery. He was first elected to the House in 2018 and took Marsha Blackburn's seat after she successfully completed a campaign for Senate.
Green's resignation reduces the Republican margin in the House.
Although Republicans are still in the majority in the House, Green's resignation means that their majority is down to 219-212, at least until his seat in a solidly red district can be filled. That narrow majority could, at least in theory, make it more difficult for the House to pass legislation.
That would be the case, of course, if the House were planning to conduct much business over the next couple of months.
Instead, news broke on July 22 that Speaker of the House Mike Johnson would be shutting the House down ahead of schedule, in part so that there would be no vote on the release of pertinent information related to Jeffrey Epstein.
"We're not going to play political games with this," Johnson said. Lawmakers were originally set to break for August on July 24, but Johnson has decided to end proceedings early to save his caucus and the president from a difficult vote.
So it doesn't seem like Green's resignation is going to have a major impact on the House's business, after all. A special election will have to be held to fill his seat, but the House will be off until after Labor Day anyway.
Given that extended absence, and the fact that Johnson doesn't seem to think there's much else worth doing in the House, he might not be too upset about Green's resignation.
Green, meanwhile, is off to start his business, and hopefully he'll share what it is at some point.
