Major Garrett, CBS News' chief White House correspondent, tweeted his fury at someone's "shirty business" on Monday.
The reporter quickly deleted the tweet, which was perhaps meant to be a direct, private message.
"The f--- I am," he wrote in the tweet. "That is shirty business what you did. Fix it. I'm not f---ing kidding."
Jim O'Sullivan, the White House correspondent for the National Journal, had cracked a joke about Garrett earlier: "Someone, @MajorCBS [5], left a thing of Cover Girl on the WH press men's room sink."
He then tweeted: "Confirmed: makeup contraband in WH men's room does NOT belong to @MajorCBS [5]. Will investigate further"
After his message, Garrett seemed to confirm that Sullivan had drawn his apparent ire.
"Monday before SOTU [the State of the Union Address] is always slow. Pity," he tweeted [6]. "I was speaking to @JOSreports [7]. He knows why. I hear S#%* is REALLY hitting the fan in Damascus."
CBS did not immediately respond to requests from TheWrap for comment.
