President Trump blasted Chelsea Manning as an ingrate Thursday for having the gall to criticize the former commander-in-chief, who commuted her lengthy prison sentence.

“Ungrateful TRAITOR Chelsea Manning, who should never have been released from prison, is now calling President Obama a weak leader,” Trump said in a Thursday morning tweet. “Terrible!”

Manning was found guilty of leaking state secrets to WikiLeaks and was ordered to serve 35 years.

In one of his last acts as president, Obama commuted Manning’s sentence, bringing it down from 35 years to seven. She’ll be released in May.

She weighed in on Obama in a Wednesday op-ed in The Guardian, saying the “one simple lesson” to draw from his legacy was: “do not start off with a compromise.”

“They won’t meet you in the middle. Instead, what we need is an unapologetic progressive leader,” she added.

Manning, who claims Obama “faced unparalleled resistance from his opponents, many of whom wanted him to fail,” says he failed to meet the moment of his presidency. She argues the president was too timid on domestic and foreign policy alike — and that liberals need someone bolder to lead them in the future.

“We need someone who is unafraid to be criticized, since you will inevitably be criticized. We need someone willing to face all of the vitriol, hatred and dogged determination of those opposed to us,” she said.

“We need to actually take the reins of government and fix our institutions. We need to save lives by making change at every level,” she concludes.

Nowhere in the op-ed does Manning actually thank Obama for commuting her sentence.
