WASHINGTON — US President Donald Trump assailed the Supreme Court yesterday after it blocked his plan to restrict mail-in ballots, launching a rare and blistering attack on the justices he hand-picked in his first term.

Trump accused the court of allowing itself to be cowed by Democrats following the ruling, which comes as a blow to Republican hopes of keeping control of Congress in November’s midterm elections.

“These are not the people I interviewed to serve on the United States Supreme Court, they are merely a shell of their original selves,” Trump said on his Truth Social network.

Trump appointed three Supreme Court justices in his first term, Amy Coney Barrett, Brett Kavanaugh and Neil Gorsuch, giving the court a conservative supermajority.

But in his lengthy social media diatribe, the 80-year-old Republican now blamed them for some of the most “destructive, hurtful, and damaging decisions in our Country’s history.”

“The Supreme Court has really let our Country down! Certain Justices are petrified of these crazed and depraved Democrats, and are totally unable to show the courage necessary to save our America,” he said.
