Feds Investigate Threat Sent to Donald Trump’s Sister

Federal authorities are investigating a threatening letter Donald Trump’s sister received in the mail a day after the mogul’s son was sent a similar letter.

NBC News, citing anonymous sources, reported that the FBI and Secret Service are probing the Friday incident involving the Republican presidential front-runner’s older sister, Maryanne Trump Barry.

Trump Barry, a federal appeals court judge in Philadelphia, was mailed a threatening letter similar to the one received by Trump’s son, Eric Trump, which reportedly warned that if Trump did not drop out of the presidential race soon, harm could come to the family’s children.

Eric Trump’s package contained a non-hazardous powdery substance inside, according to the Washington Post. Trump Barry’s did not, NBC News reports. It’s unclear if the letters were sent by the same sender.

Threats have also been delivered to Sen. Ted Cruz’s campaign headquarters in Houston and to Sen. Marco Rubio’s campaign headquarters in Washington, according to the Post.
