Piers Morgan, J.K. Rowling in Twitter fight over politics

Brits may be known for politeness and restraint, but two of England'sbest-known exports aren't holding back in a Twitter war. Or should we say row.

TV personality Piers Morgan and Harry Potterauthor J.K. Rowling sparred back and forth over American politics Friday and Saturday after Rowlingexpressed her satisfaction at a talk show clip in which Morgan had an expletive directed at him.

He said, she said

It all started when Morgan, a former CNN host and judge on Britain's Got Talent,defended the U.S. government's travel ban during an appearance on HBO's Real Time with Bill Maheron Friday.

Morgan faced off with Australian comic Jim Jefferies on the episode during a discussion of the executive order. Morgan, who has described Donald Trump as a friend in the past and appeared on Trump's former reality show Celebrity Apprentice,said it was "not a Muslim ban."

That's when Jefferies dropped the F-bomb and Rowlingdropped her first tweet, writing, "Yes, watching Piers Morgan being told to f--k off on live TV is *exactly* as satisfying as I'd always imagined."

Rowling's 'arrogance'

What followed was a flurry of exchangesbetween Rowling and Morgan, many of which used explicit language.

Morgan responded to Rowling, saying he'd never read a word of her uber-popular fantasy series. He also slammed her"superior, dismissive arrogance."

In return, Rowlingcalled Morgan a "celebrity toady" who is"fact-free and "amoral" with"bigotry-apologism."

Get the popcorn

Judging from the number of responses and growing attention, people just couldn't look away or resistchiming in, includingSilicon Valley actor Kumail Nanjiani, Star Trek legend George Takei and House of Lies star Don Cheadle.

Morgan hasmaintained a fighting spirit with hisretweets and replies but looks likeRowlingdid a mic drop.
