Fake news is giving world leaders sleepless nights and keeping not people on the edge of their seats; others have lost their seats.

Some Americans believe fake news helped to elect the wrong man as president.

Political leaders in the US are taking the bull by the horn to make sure fake news does not pull them in the wrong direction.

On Tuesday, American internet giants were invited by US congress to explain how they allowed their platforms to be exploited by peddlers of fake news.

They did admit some lapses on their part and said they were committed to cracking down on fake news operations on their platforms like the ones Russians conducted to meddle in last year's US presidential elections.

The invitation by congress came a day after bombshell indictments in a US probe of Moscow's election interference and possible coordination between President Donald Trump's campaign and Russia.

Facebook, Google and Twitter sought to assure concerned lawmakers that they were taking necessary steps to rid their platforms of disinformation, propaganda and provocation.

In their testimony, the social media companies revealed startling new data showing many more millions of Americans were exposed to the fake news than previously thought.

"We are deeply concerned about these threats," Facebook general counsel Colin Stretch told the Senate Judiciary Subcommittee on Crime and Terrorism.

"That foreign actors, hiding behind fake accounts, abused our platform and other internet services to try to sow division and discord -- and to try to undermine our election process -- is an assault on democracy, and it violates all of our values," he said.
