Anti-vaxxer Donald Trump is at it again. This time, dangerously spreading false information via Twitter.

ABC’s Jake Tapper immediately calls him on his beyond irresponsible tweets.

He then tried tweeting him directly.

Other Twitter users quickly jump in to call out Donald Trump for his asshattery and his continued preying upon the fears of parents of children with autism.

Indeed. Never get between Donald Trump and a camera. However, in this case, his gigantic-sized ego and need for attention is harming others. Jake Tapper tries to school him with some, you know, facts.

Will he listen?

FYI, Donald: Twitter users say “You’re fired.”
