President Trump slams Chelsea Manning for insulting Barack Obama with same lines.....

Evidently the only person who’s allowed to insult the old president is the new president.

President Trump condemned whistleblower Chelsea Manning Thursday for criticizing former President Barack Obama with an insult Trump himself has used against the former commander-in-chief.

“Ungrateful TRAITOR Chelsea Manning,

who should never have been released from prison, is now calling President Obama a weak leader,” he tweeted just after 6 a.m. “Terrible!”

Trump himself has frequently suggested that Obama, who left office last week, lacked leadership skills, repeatedly praising Russian President Vladimir Putin at Obama’s expense, saying the Kremlin head is a “stronger leader” than the Democrat.

The tweet came just a day after Manning penned a scathing column for the Guardian arguing that Obama compromised with his adversaries too much and thusly wasn’t the “strong and unapologetic progressive” leader many liberals had hoped he’d be.

“The one simple lesson to draw from President Obama’s legacy: do not start off with a compromise. They won’t meet you in the middle,” she wrote. “Instead, what we need is an unapologetic progressive leader.”

During his final days in office, Obama commuted Manning’s prison sentence. The former private — who was sentenced to 35 years in a military prison in 2013 for leaking classified information to whistleblowing site WikiLeaks — will be released in May following the commutation.

Her scornful op-ed marked a complete change in tone toward Obama. 

“Thank you @BarackObama for giving me a chance,” Manning tweeted last week alongside a smiling emoji with a tear of joy.

While her column is deeply critical of Obama and his legacy, Manning did not directly call Obama a “weak leader,” as Trump suggested. She pointed out that Obama’s opponents called him weak, and she criticized him for attempting to compromise with rivals who mocked him — but she didn’t directly use the term against him.

“When it came to foreign policy, even though he was only carrying out the expanding national security policies of the previous administration, they would ceaselessly criticize him for being too weak, or too soft or too sympathetic,” she wrote. “After months of comprise on his end, they never cooperated a single time.”
