Elon Musk has entered into another social media spat with a prominent politician, this time dubbing Sen. Elizabeth Warren "Senator Karen."
In a quarrel over taxes, the two took to Twitter to air their dispute. "Let's change the rigged tax code so The Person of the Year will actually pay taxes and stop freeloading off everyone else," Warren tweeted on Monday alongside a link to a story about Musk being named Time Magazine's 2021 person of the year.

Musk fired back on Tuesday, stating, "And if you opened your eyes for 2 seconds, you would realize I will pay more taxes than any American in history this year. Don't spend it all at once … oh wait you did already."
The Tesla Motors CEO then related Warren to slang for an obnoxious woman. "Please don't call the manager on me, Senator Karen," Musk wrote.
In November, Musk engaged in an altercation with Sen. Bernie Sanders after the politician tweeted, "We must demand that the extremely wealthy pay their fair share. Period." In retaliation, Musk retorted, "I keep forgetting that you're still alive."
Musk has yet to comment, on Twitter or otherwise, on the recent shooting death of a person at the Tesla Fremont factory. Neither Musk nor the electric vehicle company has made any public statement acknowledging the death, which is being investigated as a homicide.
Fremont police have reported that the victim was a Tesla employee. Tesla has not yet responded to KCBS Radio's request for comment confirming that the victim worked at the factory.
