Emergency crews responded Monday after a letter containing an unidentified white powder was sent to the Florida home of Donald Trump Jr., the eldest son of former President and GOP front-runner Donald Trump.

A person familiar with the matter said that results on the substance were inconclusive, but officials do not believe it was deadly. The person spoke on condition of anonymity to confirm details of the letter, which were first reported by The Daily Beast.

Trump Jr. opened the letter, which also contained a death threat, in his home office, and emergency responders wearing hazmat suits responded. It's the second time white powder has been sent to the former president's oldest son.
