President Donald Trump's attack on hospitalized Buffalo protester Martin Gugino drew widespread shock and condemnation on Tuesday.

In a tweet posted early in the morning, Trump suggested that the 75-year-old Gugino, who is still in the hospital after being shoved to the ground by police and hitting his skull on the pavement, could be an "ANTIFA provocateur" who intentionally injured himself to make the police look bad.

"I watched, he fell harder than was pushed," the president wrote. "Could be a set up?"

The reaction to Trump's tweet was fierce and harsh, as many people called out Trump for attacking an elderly man who was shown on video bleeding from his ear after his head hit the ground.
