Politicize all teh thingz!
Yes, it's all due to "President Trump's partial federal government shutdown". Herdthink among tech and media leads to biased misattributions like these. It takes uncompromising positions on both sides of the partisan aisle to shut down the US government until key spending bills can be passed. Shamir can blame Democrats and Republicans for any backlog (if that's what it was, since that was pure speculation) just much as he should blame himself for trusting government at all and failing to follow up on such an important item. But Orange Man Bad, I guess.
