The PROTRUMP community on REDDIT is infamous....

"Many in the subreddit, which has over 441,000 members, took it as validation that the president reads the pro-Trump community that has long promoted alt-right views attacking Islam, minorities, and immigrants. HanA--holeSolo is a frequent participant of such conversations."

Trump's violent CNN video likely came from Reddit user HanAssholeSolo - Business Insider

This is the President of the United States of America.

A little more about this what is called a "sub" Reddit called TheDONALD....

"Minutes after the video was tweeted, commenters on pro-Trump subreddit The_Donald rejoiced, believing they had been the source of the President’s post. “This is just unbelievable. I am in love with our President,” wrote user Ace_Suburb."

"The_Donald is well-known as a cesspool for unabashed racism. Frequent poster HanAssholeSolo, who created and posted the CNN wrestling video clip four days ago, often refers to African-Americans, women, and Muslims using slurs. He or she attacks Black Lives Matter, Islam, feminism, liberals, and, bizarrely, the state of Maryland, and references fake news outlet Infowars.
After Trump’s tweet Sunday morning, HanAssholeSolo wrote “Wow!! I never expected my meme to be retweeted by the God Emperor himself!!!”
The user also started editing the worst obscenities and slurs out of his or her post history, eliminating the n-word, for example, and deleting a remark about killing all Muslims. Quartz had taken screenshots of HanAssholeSolo’s Reddit history earlier, however, so you can see how the posts looked before they were edited."

Here are a few original posts from this guy who Trump follows and retweeted....
