Stephen Colbert explains why Donald Trump is like Transformers villain Megatron

US President Donald Trump has been compared to a number of famous entertainment villains, from Harry Potter's Voldemort and The Dark Knight's Bane, to Lex Luther from Superman, so it comes as no surprise that one of his biggest critics on late night TV has added to the list.

The Late Show's Stephen Colbert has no qualms about expressing criticism for the American president and on 3 April compared him to yet another big screen baddie. The talk show host was discussing the Trump administration's alleged links with Russia and the recent claims that Kremlin hired 1,000 internet trolls to flood the web with fake stories about Hillary Clinton during the elections to tarnish her image.

The most effective thing Russia did was change public opinion through targeted media.

"When I say fake news, this is real fake news, not fake fake news that is real news that Donald Trump just doesn't like," Colbert said.

Quoting ABC News, Colbert explained how Russia allegedly used Twitter-bots to spread fake news stories and "fool users into believing misinformation" by artificially increasing the number of times the stories were shared and retweeted.

"Because if enough people say something is popular, I might trust that it's good," said Colbert. "It's like how if one person tells me how Transformers is a good movie, I might not see it. But if everyone on Facebook is raving about it, I'll go. And by the time I realise I was lied to, Megatron is president," he quipped.

"Do not vote for the Decepticons."
