Donald Trump says he's got "many, many millions of people" behind him, but apparently not everyone is a Donald devotee. Someone who apparently falls into the latter camp took out their frustrations via his 32-year-old son, Eric, who is said to have received a threatening letter Thursday in an envelope laced with a white powder, CBS News reports. A Trump Organization source confirmed to ABC News that the suspect mail was sent to Eric's ritzy 14th-floor apartment in Trump Parc East, located on Central Park South in NYC. The NYPD confirmed only that it responded to a call at the building around 7:15pm and that no injuries were reported.
The letter, which the New York Post says was opened by Eric's wife, Lara Yunaska, had a postmark from Massachusetts and issued a warning that if Donald Trump doesn't cease his presidential run, harm would befall his kids, a source close to the probe tells CBS. White powder reportedly fell out of the envelope when Yunaska opened it, and a source says the powder has been sent out for lab testing, though a preliminary field test noted the unknown substance didn't appear to be dangerous. The NYPD wasn't taking any chances, though, with the New York Daily News reporting that members of the department's Emergency Services Unit were spotted at the scene around midnight hauling bright-red bags with the word "hazardous" prominently displayed. Along with city police, the FBI and Secret Service are also said to be investigating the incident.
