Citing a report by pro-Trump channel One America News Network, Trump wrote that the protestor, Martin Gugino, could be a member of the anti-fascist movement antifa, which the president and other Republicans have blamed for violence at the protests.
Trump offered no evidence of links between Gugino and the movement.
"Buffalo protester shoved by Police could be an ANTIFA provocateur. 75 year old Martin Gugino was pushed away after appearing to scan police communications in order to black out the equipment. @OANN I watched, he fell harder than was pushed. Was aiming scanner. Could be a set up?" Trump tweeted.

His post appeared just hours before the funeral in Houston of Floyd, an African American who died on May 25 after a white police officer in Minneapolis pinned him with a knee to the neck for nearly nine minutes.
Two Buffalo police officers have been arraigned on felony assault charges after a viral video showed one of them shoving Gugino and the other walking past his still body after he fell to the sidewalk. As Gugino tumbles, his head strikes the pavement and trickles blood, according to the video.
Erie County District Attorney Erie County District Attorney John Flynn, who is prosecuting the officers, declined to comment on Trump's tweet about Gugino, who remains hospitalized.
Lawyers for the two officers as well as Gugino did not immediately respond to a Reuters request for comment.
But New York Governor Andrew Cuomo jumped into the fray, saying he was "disgusted" by Trump's tweet and urged the president to apologize.
"He accused this man of being associated with antifa - no proof whatsoever. No facts, just an assertion," Cuomo said at his daily news briefing. "I mean, if there was ever a reprehensible, dumb comment, and from the president of the United States," said Cuomo, a Democrat.
