Published September 30, 2026

Ted Cruz Zodiac Killer is a joke conspiracy theory claiming that Texas senator Ted Cruz is the unidentified serial killer who terrorized Northern California in the late 1960s. Born on Twitter in 2013 and revived through the 2016 presidential campaign, the gag went from niche shitpost to one of the defining political memes of the decade, eventually acknowledged by Cruz himself.

Overview

Ted Cruz Zodiac Killer is a running political joke that Texas senator Ted Cruz is secretly the Zodiac Killer, the unidentified murderer who killed at least five people in the San Francisco Bay Area in 1968 and 1969 and taunted police with cryptic ciphers3. The bit is deliberately absurd, everyone repeating it knows Cruz was born in 1970, which makes the accusation physically impossible3. That impossibility is part of the joke's charm, the whole thing is a shitpost dressed up as a criminal investigation.

The humor works on two levels. The surface layer plays the theory straight, complete with fake deathbed confessions, evidence boards, and puns like the claim that the Zodiac's first victims were named "Cal and Gary" because Cruz was born in Calgary1. The subtext, spelled out by a Verge writer in 2017, is that the meme caught on because a lot of people think Cruz is "loathsome enough to murder people" and the format lets them say so through a joke6. NPR interviewed several of the accounts pushing the bit in early 2016 and found the same undercurrent, most of them just said they found Cruz "creepy"3.

By 2016 the joke reached escape velocity. Google's autocomplete filled in "Is Ted Cruz the Zodiac killer?" before you finished typing his name3, a Facebook page racked up thousands of likes8, and a comedian roasted Cruz with it at the White House Correspondents' Dinner3. A year later Cruz himself tweeted a picture of a Zodiac cipher in response to another senator, effectively canonizing the joke from inside the Senate6.

The earliest known post is a March 14, 2013 tweet from the account @RedPillAmerica during CPAC, which joked that Cruz's upcoming speech was titled "This Is The Zodiac Speaking"2. The tweet drew on a phrase the real Zodiac Killer used to open his letters to the press, and it sat quietly for over a year before other accounts started building on it.

On November 10, 2014, Twitter user @Flash2844 posted that Cruz's deathbed confession would be "I am the Zodiac Killer," attaching the hashtag #TedCruzIsTheZodiacKiller and giving the joke a searchable label7. From there it stayed as a low-level Twitter in-joke through most of 2015, waiting for Cruz's presidential run to give it a wider audience.

How It Spread

The joke moved from Twitter shitpost to mainstream media property across roughly three years. On December 15, 2015, a Facebook page called "Ted Cruz is the Zodiac Killer" launched and picked up more than 9,400 likes over the next two months8. Twitter users kept adding lore, on January 20, 2016 user @Lindzeta posted a fake confession quote and later that day @ZeppoWilbury tweeted the Calgary / "Cal and Gary" pun that became one of the most repeated bits in the whole run1.

The real turning point was a February 13, 2016 stunt by @vrunt, who asked followers to mass-Google "Ted Cruz is the Zodiac Killer" so the phrase would show up on Google Trends. It worked well enough that the query appeared on-screen during CBS's broadcast of the Republican presidential debate that night, and @vrunt posted a screenshot captioned "holy shit we did it"1. Within two weeks NPR ran a segment titled "Meme Of The Week: Ted Cruz And The Zodiac Killer"3 and The Verge published a long walk-through of the "evidence"4. On April 30, 2016, comedian Larry Wilmore hammered the line at the White House Correspondents' Dinner, and Yahoo News followed up by asking Cruz's wife Heidi about it, she said she'd been married to him for 15 years and "it doesn't bother me at all"3.

The most famous single moment came on October 18, 2017. Senator Ben Sasse spilled a Dr. Pepper on Cruz during a Sessions hearing, the two traded jokes, and after a reply about a "Lee Harvey Oswald Was Framed" t-shirt, Cruz tweeted an image of the Zodiac Killer's cipher with no caption5. The tweet passed 47,000 retweets and 80,000 likes inside a day9, Twitter built a Moments page around the reaction, and The Verge, New York magazine and The Hill all covered it as Cruz personally euthanizing the meme65. On r/nottheonion, user Chumunga64's post about the tweet passed 25,000 points and 1,000 comments in 18 hours10.

How to Use This Meme

The format is loose. Most versions treat the accusation as settled fact and then either invent "evidence" (fake quotes, doctored maps, puns on Cruz's birthplace) or drop the line into unrelated conversations about Cruz as a punchline. A common convention is to write it as a hashtag or Google search suggestion, playing on the Google autocomplete result that briefly surfaced during the 2016 primary3. Cruz himself demonstrated the deadpan version in 2017 by tweeting the Zodiac's cipher with no caption, letting the image do the joke5.
