White House quiet on source of Trump's CNN attack video

The White House has remained quiet over the source of a video that Donald Trump used to attack CNN on Twitter.

Over the weekend, Trump issued a tweet that showed him taking down WWE boss Vince McMahon, which was part of a wrestling event the pair were involved in. But superimposed over the face of McMahon was the CNN logo.

It has emerged that the original source of the video was Reddit user who has posted anti-Semitic and anti-Muslim posts in the past.

However, the White House denied that the Reddit user was the source, saying: "The video was not pulled from Reddit."

The Anti-Defamation League (ADL) said that the video was originally posted by a user named 'Han-------Solo'.

The user wrote about the tweet saying: "Holy s***!! I wake up and have my morning coffee and who retweets my s***post but the MAGA EMPORER himself!!! I am honoured!!"

But ADL CEO Jonathan Greenblatt said that the user has a "consistent record of racism, anti-Semitism and bigotry. We must condemn these extremists and keep them on the margins of our society."

Tom Bossert, Trump's homeland security adviser said that Trump was a "genuine president expressing himself genuinely. "I think that no one would perceive that as a threat. I hope they don't. But I do think that he's beaten up in a way on cable platforms that he has a right to respond to."

The White House declined to answer further questions about the video including its origin, the vetting process or how Trump was made aware of it.

Trump's recent tweets have sparked outrage in some circles following his attack on Morning Joe hosts, Joe Scarborough and Mika Brzezinski, as well as his attempts to discredit news sources which he believes to be "fake news."
