Not even personal email accounts are safe when your expletive-laden missive makes its way to K Street.

As my Heard on the Hill colleague Warren Rojas reported Wednesday, a House legislative assistant is out of a job after his excoriation of his roommate and Small Business Committee staffer became afternoon email entertainment.

From the story:

As is often the case between feuding bros, the source of the intrahousehold friction appears to be a woman: a newly minted fiancee, to be exact.

Per Urteaga’s NSFW complaint, Leieritz had become a “backstabbing little b—-” since slipping his lady a ring, a situation that has escalated into a “War of the Roses”-style battle for control of their homestead.

“Most recently, he went behind my back and told my landlord that I was planning on moving out, which is not true. We both are on the lease, hes [sic] the one decided to get married and start a new future; therefore, he should take it upon himself to find a new place for them to start their lives together. Common sense…right?” Urteaga preached from a personal email account.

The backbiting only intensified from there, with Urteaga attacking Leieritz’s and his betrothed’s character (“They sure are the religious and godly couple they want you to perceive of them, aren’t they?”) before insulting the very people he is presumably attempting to win over (“No need to respond to this. To be honest, I could care less what you have to say.”).

Hill Navigator rules of thumb for having a meltdown:

• Don’t do it over office email.
• Don’t do it via mass email.
• Remember your words are your own, even off the record can’t protect you all the time.

Best-case scenario: Keep your meltdowns confined to loved ones at home, not colleagues in the office next door.

Correction: 1:35 p.m.

An earlier version of this post incorrectly stated that both staffers worked for the Small Business Committee. Only Leiritz does.
