Ethan Czahor, a newly-hired aide to Jeb Bush's campaign-in-waiting, resigned today after controversy about his past offensive tweets and remarks. Czahor was to be Bush's chief technology officer. He had co-founded the website Hipster.com , a social network eventually purchased and then phased out by AOL. But reporters soon noticed that Czahor had a history of tweets and comments joking about women, gays, and blacks. Bush's team deemed his remarks "insensitive" and, one day after Czahor's hiring was first reported, announced that he had stepped down.

Controversy and resignation

Reporters didn't take long to notice that Czahor had a history of tweets and comments that seemed out of place for a presidential campaign aide.

As Andrew Kaczynski of BuzzFeed News reported, several of these tweets joked about "sluts," including one that read, "New study confirms old belief: college female art majors are sluts, science majors are also sluts but uglier." Others referenced gays — Czahor tweeted that a San Francisco Gold's Gym was full of "men who undress you with their eyes while you work out."

And earlier today, Igor Bobic of the Huffington Post reported on a 2008 blog post in which the college-aged Czahor praised Martin Luther King Jr. not having "his pants sagged to his ankles" or delivering his speech in "jibberish." King didn't "drone on about every little problem a black person has faced in their life," Czahor wrote.

In a Tuesday statement announcing that Czahor was stepping down, an aide to Jeb Bush wrote that his "regrettable and insensitive" comments "do not reflect the views of Governor Bush or his organization and it is appropriate for him to step aside."
