Today has been weird, so let's recap. During Wednesday's Senate Judiciary Committee hearing with Attorney General Jeff Sessions, Republican Sen. Ben Sasse said he "dumped a Dr Pepper on Senator Cruz."

Sasse just said he dumped a Dr Pepper on Ted Cruz. He just became the 2020 frontrunner.

Both senators exchanged jokes about it on Twitter.

And that's when things escalated. Sasse made a joke referencing a conspiracy theory , which Donald Trump promoted during the 2016 presidential campaign, that Ted Cruz's father was involved in the JFK assassination.

For those in need of a weird–internet catch-up: This is the cipher of the Zodiac Killer, an unidentified serial killer who claimed to have killed 37 people in California in the '60s and '70s.

There's a popular/fake conspiracy-theory-turned-meme that Ted Cruz is, in fact, the Zodiac Killer.
