are the left wanting to Kill Kavanaugh?

Typing a word “kill” into Twitter search returns an appalling drop-down result – it turns out that #KillKavanaugh currently appears to top the list of search and hashtag suggestions.

The bizarre search suggestion was spotted earlier on Monday by Instapundit, a libertarian blog run maintained by Glenn Reynolds, a law professor at the University of Tennessee. The notable find comes just days after fresh episodes of a saga involving the federal judge Brett Kavanaugh and sexual assault claims against him.

Currently, at the time of composing this article, #KillKavanaugh is the first autocompleted suggestion in searches for “kill.”

So the first autofill on #Kill is #KillKavanaugh. @jack, how is this happening. pic.twitter.com/R2vhYtTpe2

That said, by typing this word into the Twitter search, users might easily come across the hashtag discussing the death of Donald Trump’s pick for the Supreme Court.
