“What I think you ought to do is boycott Apple until such time they give that security number,” Trump said at a rally in South Carolina. “How do you like that? I just thought of it: Boycott Apple.”

“Tim Cook is trying to do a big number,” he added, referring to the Apple CEO. “Probably to prove how liberal he is.”

Apple is a frequent Trump target, most recently for building most of its devices in China. But the real estate developer, as Mic and many Twitter users noted, also uses his iPhone to send dozens of tweets a day.

According to Twitter’s API, Trump has sent 101 tweets from his iPhone, 87 from his Samsung, and four from the web client.

As for his supporters, not so much: Mic also noted that “Trump has the lowest concentration of iPhone users of any presidential primary candidate.”
