Early Thursday morning, Trump did it again. This time, he retweeted a supporter who pretty clearly appeared to suggest that the shootings in San Bernardino, Calif., on Wednesday — shootings that killed 14 and injured 17 — would help Trump's "poll numbers."
And below is the context of the tweet Trump forwarded to his followers. As you can see, the previous commenter suggested Trump would get a bump from saying "no more muslim immigration to america." In response, the Twitter user that Trump retweeted said, "his poll numbers jump every time instances like this occur."
The tweet is a pretty clear reference to the San Bernardino shootings, given they dominated the news over the past 18 hours and that one of the suspects, Syed Rizwan Farook, has been identified as a devout Muslim.
