A Georgia state trooper was treated and released from a Cleveland hospital after a protester threw an unknown liquid on him during a demonstration near the Republican National Convention.

Capt. Mark Perry, a spokesman for the Georgia Department of Public Safety, e-mailed The Atlanta Journal-Constitution on Thursday evening to say the unnamed officer “complained of tingling and numbness.” Perry didn’t know whether the protester had been taken into custody.

It was unclear what caused the numbness — syringes, stickers or something else.

Local media reports said protesters placed yellow stickers on two officers’ arms during a Thursday protest that read, “I am awesome.” Their arms reportedly soon went numb. Police are testing the stickers.

A sticker was placed on a third officer and his neck went numb, according to television station WXIX.

It wasn’t clear whether the protesters were associated with the Stand Together Against Trump protest. A few dozen demonstrators had gathered in downtown Cleveland.

Cleveland police have now added syringes to the prohibited items list.

Establishment has Trump’s back

The Republican establishment that Donald Trump so loathed during his primary fight came to his aid during this week’s Cleveland bash, helping him overcome last-minute challenges and closing ranks around him after Texas U.S. Sen. Ted Cruz’s striking snub.

And nowhere was that more apparent than the speech Thursday by Republican National Committee Chairman Reince Priebus. He declared that the New York businessman was nothing short of a savior riding to the nation’s rescue.

“I have a message to America: Hold on,” he said. “Help is coming.”

Trump, Priebus said, was the tonic to the nation’s most pressing challenges: He would bring back jobs, stop illegal immigration and protect Second Amendment rights.

“Donald Trump wants to make sure you can pay the mortgage, put gas in the car, and buy new clothes for the first day of school,” Priebus said. “Donald Trump is committed to hitting terrorists hard and making the safety of every man, woman, and child in America his No. 1 priority. No more negotiating with terrorists. If they want to take us down, we will take them down.”
