President-elect Donald Trump is expressing his concern over President Obama's decision to commute the sentence of ex-Army analyst Chelsea Manning.

Manning was convicted of exposing more than 700 classified government and military documents to the website, WikiLeaks.

Trump's incoming press secretary Sean Spicer says the President-elect feels the decision sends a "troubling message."

However, Obama says Manning's sentence does the exact opposite.

"The notion that the average person who was thinking about disclosing vital classified information would think that it goes unpunished I don't think get that impression from the sentence that Chelsea Manning had served," Obama said.

Manning will be released in May after serving six years of a 35-year sentence.
