"after the FBI discovered Democratic Party computers were hacked — a breach later blamed on Russia."
Not by anyone to be taken seriously. Craig Murray, who picked up the DNC emails from their leaker and delivered the DNC emails to WikiLeaks has publicly testified that the leaker is a DNC employee who was "disgusted" by corruption in the DNC and by the rigging of the DNC primary nomination in favour of Hillary. The claims by the USA MSM are just a big nothing burger.
"In a news conference before he flew to Germany, Trump again refused to unequivocally accept the conclusion by multiple U.S. intelligence agencies that Russia interfered to try to help Trump win last November. "
Let's be clear: 0 USA intel agencies concluded that. 2-dozen hand-picked individuals from 3 agencies put together a report which they were in disagreement of concerning its conclusions. 0 agencies worked on the report, and 0 agencies were in agreement over the report. G&M should stop peddling nothing burgers.
