A hazmat team and fire trucks responded to the Jupiter, Florida home of Donald Trump Jr. Monday after he received a letter with an unidentified white powder inside.
Trump Jr. says he opened the letter, and the white powder flew out.
Initial tests were inconclusive, but authorities don't think the powder is deadly.
The Jupiter Police Department has yet to respond to requests for comment on the incident.
