Trump first waded into this controversy six days ago on Fox & Friends. Now he doubles down with this Tweet. Not only does he repeat his assertion that autism is caused by vaccines, but he appears to goes one step further. We aren’t completely sure, but he seems to be saying that the U.S. Food and Drug Administration should prohibit physicians from administering multiple vaccinations during a single visit:

Now they say obese women may cause Autism in children- nonsense, they use any excuse. The FDA should immediately stop mass dose vaccinations. If you spread single doses out over a short period of years, Autism would be greatly reduced. It’s just my opinion, but I know I’m right. Many people have noticed the problem only after the massive shot.
