President Trump is reportedly 'stressed out, isolated, and gaining weight'

As pressure mounts amid a growing investigation into relations between the White House and Kremlin officials, President Donald Trump is becoming increasingly isolated and stressed by presidential demands, according to a new report.

"He now lives within himself, which is a dangerous place for Donald Trump to be," a source reportedly close to the president told CNN. "I see him emotionally withdrawing. He's gained weight. He doesn't have anybody whom he trusts."

Prior to his first foreign trip to Europe and the Middle East, Trump was already "in a pretty glum mood," the source revealed.

However, woes further intensified upon the president's return after reports arose pinning members of his inner circle, notably, his son-in-law and close adviser, Jared Kushner, as persons of interest in the FBI probe.

Last week, the Washington Post reported that Kushner proposed establishing a backchannel line of communication between Trump's transition team and Kremlin officials.

Trump has dismissed the allegations as the work of "fake news media" early Sunday morning on Twitter.

According to CNN's source, the president has been receiving advice from aides and officials, but there's apparently concern over whether Trump is even taking in the information.

"No one is giving him the landscape—this is how it works, this is what you should do or not do," the close source told CNN. "And no one has enough control—or security—to do that."

Instead, the source said Trump is waiting for his team to quell the fallout.

"He's sitting there saying, like he does with everything, 'You guys work for me. Fix this,'" the source added.
