A Democratic activist has been charged after police say he sent hoax white powder to the son of President Trump.

Heavy.com reports:

A 24-year-old Massachusetts man is accused of sending a threatening letter containing white powder to Donald Trump Jr.’s New York City apartment, along with mailing threats to several other people around the country, federal prosecutors say.

Daniel Frisiello, of Beverly, was taken into custody Thursday and faces multiple federal charges. The letter containing white powder, which turned out to be harmless, was opened by Trump Jr.’s wife, Vanessa Haydon Trump. She was taken to the hospital as a precaution, according to NBC News.

“You are an awful, awful person. I am surprised that your father lets you speak on TV,” the letter allegedly written by Frisiello said.

“You the family idiot. Eric looks smart. This is the reason why people hate you. You are getting what you deserve. So shut the f*** up.”

The Rebel’s John Cardillo notes Frisiello is a Democratic activist.

The FEC record tweeted by Cardillo shows Frisiello donating $75 to ActBlue, a Democratic organization that supports candidates.

Act Blue donated has given to Frisiello’s senator, Elizabeth Warren.

The record also showed Frisiello as “not employed.”

Heavy notes Frisiello “has shared and commented on several news articles critical of President Donald Trump and Republicans.
