President's Trump's deputy national security adviser reportedly gave the president fake information, leading to a crackdown at the White House.

K.T. McFarland handed the president a printout of two covers of Time magazine, Politico reported, citing four White House officials familiar with the matter.

One of the covers appeared to be from 1970 and issued a warning of a coming ice age. The other cover was from 2008. That one was about surviving global warming.

But the cover from 1970 was fake and part of an internet hoax, according to Politico.

One official tried to defend McFarland's error.

“While the specific cover is fake, it is true there was a period in the 70s when people were predicting an ice age,” an official told Politico.

“The broader point I think was accurate.”

After the incident, White House chief of staff Reince Priebus warned senior staff not to try to slip information to the president, according to the news outlet.

The president often blasts the media, accusing reports of dishonest and biased coverage against him.

He frequently refers to certain articles or news outlets as "fake news."

Earlier this month, he questioned on Twitter when the "Fake Media" would ask about the Democrats' dealings with Russia and why it declines to report that ObamaCare is "on its last legs."
