He Didn't Know

Or, alternative fact: He didn't care.

On Wednesday, it was revealed that from September to November last year, while he was working as a top adviser to Trump’s presidential campaign, [his briefly former national security adviser Michael] Flynn was lobbying for a firm linked to the [the Turkish president, Recep Tayyip Erdoğan], earning $530,000. He and his company Flynn Intel Group Inc filed retroactive documents with the Department of Justice two days ago to register as a foreign agent.

Under the Foreign Agent Registration Act, US citizens who lobby on behalf of foreign governments or political entities must disclose their work to the justice department. Willfully failing to register is a felony, though the justice department rarely files criminal charges in such cases.

Because why have a law you are not going to enforce? Because enforcement is political?

Trump was unaware his former national security adviser Michael Flynn was working as a “foreign agent” when he gave him the job, according to his press secretary.

“I don’t believe that was known,” said Sean Spicer, when asked by reporters at his regular press briefing on Thursday.

[...]

“I don’t know what was discussed prior to the appointment in terms of his background, his résumé, his client base.”

He doesn't know what was discussed, but he "believes" T-Rump didn't know about Flynn's lobbying for Erdogan.

Flynn resigned in February after just four weeks as national security adviser when it came to light that he had misled the vice-president, Mike Pence, about phone conversations with the Russian ambassador about sanctions in December.

When it came to light that there were other problems as well, no doubt. A lobbyist for Turkey who was discussing sanctions with the Russian ambassador.

 ...but hey, do what you want...you will anyway.
