Mr. US Official is slightly less believable than Clapper under oath. But hey, whatever furthers your agenda.
Since we are quoting Clapper:
"I think, in many ways, our institutions are under assault, both externally — and that's the big news here, is the Russian interference in our election system," said James Clapper, the former director of national intelligence. "I think as well our institutions are under assault internally."
When he was asked, "Internally, from the president?" Clapper said, "Exactly."
Keep digging.
