The WikiLeaks founder noted on Twitter today that bots are supporting the Trump critic and darling of Democrats.
Assange posted screen captures of several of examples of what he calls bot activity.
They show several accounts tweeting the same article, titled "John McCain just made a startling public accusation against Trump amid phony Nunes memo release," at exactly the same time.
One Twitter user, @LoudaCristy, pointed to a suspicious-looking site called "LineJournal.org."
That website published a pro-McCain article reporting on his criticism of Trump.
So did @milenbu and @DaryaBoyko4, as well as @petrina_liza.
"Despite his illness, McCain showed that he has one of the great minds in public life and remains a true American hero who stands up for his country first," it reports.
"McCain did not do a very good job when he ran for president, but he continues to show that he has the intelligence, experience, and savvy that a good president needs, unlike Trump, who has turned out to be a partisan who cares more about himself than America," it said later in the article.
