From NBC News:
U.S. intelligence officials now believe with “a high level of confidence” that Russian President Vladimir Putin became personally involved in the covert Russian campaign to interfere in the U.S. presidential election, senior U.S. intelligence officials told NBC News.
Two senior officials with direct access to the information say new intelligence shows that Putin personally directed how hacked material from Democrats was leaked and otherwise used. The intelligence came from diplomatic sources and spies working for U.S. allies, the officials said.
Putin’s objectives were multifaceted, a high-level intelligence source told NBC News. What began as a “vendetta” against Hillary Clinton morphed into an effort to show corruption in American politics and to “split off key American allies by creating the image that [other countries] couldn’t depend on the U.S. to be a credible global leader anymore,” the official said.
