BUFFALO, N.Y. (WIVB) — As Martin Gugino, the 75-year-old protester who was pushed by police, remained hospitalized, President Donald Trump suggested the man could have ties to Antifa.

On Tuesday morning, Trump gave his opinion on the matter, alleging that Gugino “could be an ANTIFA provocateur” and stating, “Could be a set up?”

Antifa, short for anti-fascists, refers to a group whose political beliefs lean left.

On Monday afternoon, Kelly Zarcone, a lawyer representing Gugino, said he is “still hospitalized and his condition remains largely unchanged. He is in serious but stable condition.” Zarcone added that Gugino’s “brain needs time to rest and recover.”

Gugino was injured by Buffalo police when they shoved him during a protest. In a video, Gugino was seen bleeding from the head after being knocked to the ground outside City Hall.

“Martin has acknowledged and sincerely appreciates the tremendous outpouring of support he has received nationwide,” Zarcone said.
