Note that the Trump tweet that Dan Barry is pointing to in his tweet (to which Maggie has replied,) that Trump tweet has been deleted. But that several other tweets on topic are still on Trump's feed.

Edit to add: The Daily Beast story suggests how Trump's attention was drawn this time, via Lou Dobbs on TV:

The PJ Media story caught the eye of Fox Business pundit Lou Dobbs, who tweeted it at Trump on Sunday, and on Monday night ran a Fox Businesssegment on the story. The segment featured an interview with Diamond and Silk, the Trump promoters who falsely claimed that Facebook “censored” them without attempting to contact them. (Emails from Facebook reveal that the social media company made multiple attempts to reach the duo.)

I am trying to stay away from helping him drive the news cycle with his outrage of the day stuff, HOWEVER, this one instance is straight out about driving the news cycle, so I think it's important.

He's not ready to let up on this one, 9 hrs. ago he tweeted somebody else's video about pro-Obama & anti-Trump "Google Bias" and used the hashtag #StopTheBias.
