After Former Florida Gov. Jeb Bush sparked criticism for stumbling through an attempt to clarify his remarks about “anchor babies” on Monday, Donald Trump went after the GOP contender on Twitter.

In a long string of retweets in Trump’s feed, one Twitter egg took issue with Bush speaking Spanish during a campaign stop near the border:

“@YoungYoung54: @JeriHyatt @megynkelly @JebBush So true. Jeb Bush is crazy, who cares that he speaks Mexican, this is America, English !!” — Donald J. Trump (@realDonaldTrump) August 25, 2015

While the social media maxim that retweets don’t necessarily equal endorsements is certainly in play, Trump frequently uses his Twitter account to retweet praise from supporters and to attack his opponents.
