It’s been exactly two weeks and given the prior feedback and medical advice shared by Dr Ronny Jackson, it looks like he was correct.  Dr Jackson said given Trump’s health status he expected the cartilage and flesh to naturally close on the wound in two weeks.

Good genetics + Good prayers for healing = Good outcome

Also, President Trump has said he will NOT STOP holding outdoor rallies!

“I WILL CONTINUE TO DO OUTDOOR RALLIES, AND SECRET SERVICE HAS AGREED TO SUBSTANTIALLY STEP UP THEIR OPERATION. THEY ARE VERY CAPABLE OF DOING SO. NO ONE CAN EVER BE ALLOWED TO STOP OR IMPEDE FREE SPEECH OR GATHERING!!!” ~ President Trump
