Trump’s sister receives threatening letter

WASHINGTON — A day after his son received a suspicious package in the mail in Manhattan, Donald Trump’s older sister was sent a threatening letter — putting the entire family on edge, law enforcement sources told The Post.

Trump’s older sister, federal Judge Maryanne Trump Barry, received the threatening letter Friday at her Philadelphia home, the source said.

The letter to the 78-year-old judge was similar to a hostile note received by Trump’s 32-year-old son, Eric, the source confirmed.

On Thursday, police were called to Eric Trump’s home to investigate a suspicious white powder enclosed in a letter demanding that the billionaire Republican front-runner drop his White House bid or his family would be harmed.

Eric’s wife, Lara, opened the letter at their Trump Parc East home. Police deemed the white substance nonhazardous.

“Multiple Trump relatives have been told to be mindful of the mail threats and what they are opening,” another federal law enforcement source told The Post. “Anything suspicious, they immediately call authorities.”

Trump is the only GOP candidate to have Secret Service protection. Democratic candidates Hillary Clinton and Bernie Sanders have security details, but Ohio Gov. John Kasich and Sen. Ted Cruz do not, according to a Secret Service spokesman.
