Rep. Eric Swalwell Appears to Fart Live on TV, Network Mug Blamed

Rep. Eric Swalwell seemed to cut the cheese live on national TV ... but the cheese, as it turns out, was apparently a studio mug.

The California congressman was doing an interview Monday on MSNBC's 'Hardball' with host Chris Matthews -- and while he was going on and on about Ukraine and alleged malfeasance by DT ... something that sounded like a loud, wet fart blasted through the airwaves.

It certainly seemed like flatulence, and Rep. Swalwell even paused a moment right afterward in what many viewed as an acknowledgment of the ripped gas. And, of course, #fartgate and #shartgate soon started to trend everywhere on Twitter as a result.

Funny enough, the official 'Hardball' account excused the noise away as someone dragging a coffee mug across a table in the studio -- which just happened to get picked up on a mic.

Swalwell was ecstatic, quickly using the network's cover as what he described as "TOTAL EXONERATION!" -- very Trump-like, right?! And yes, everyone had a good laugh over it -- Republicans and Dems alike. It might've been the most uniting thing in a while, actually.

And, for those looking to go even deeper down the rabbit hole ... some have pointed to a theory that the would-be fart actually came from Matthews. Apparently, there's a history of gas being passed on his show over the years, as one Twitter user dutifully pointed out.

Anyway, if these impeachment hearings are lacking pizzazz -- as NBC News itself noted last week -- then Swalwell (or Matthews) just dropped a much-needed fun fart bomb.
