US Representative Jared Moskowitz said on Friday he was informed by police of a potential plot on his life and that a suspect was arrested not far from the Democrat’s Florida home with a rifle and a manifesto that included antisemitic rhetoric.

Moskowitz, who won reelection on Tuesday in Florida’s 23rd congressional district, said in a social media post that a convicted felon with a suppressor and body armor was apprehended by authorities. A target list that had only Moskowitz’s name on it was also found with the suspect, according to the lawmaker.

“I am deeply worried about congressional member security and the significant lack thereof when we are in the district,” Moskowitz wrote.

There has been growing concern about political violence in the United States.

Republican President-elect Donald Trump was wounded on an ear in an assassination attempt in Pennsylvania in July. A man was charged with attempted assassination in September after allegedly positioning himself with a rifle outside one of Trump’s Florida golf courses.
