Former Florida Gov. Jeb Bush's political action committee (PAC) has gotten some heat thrown its way over a new hire's past Tweets.

Chief Technology Officer of Right to Rise PAC Ethan Czahor, co-founder of Hipster.com, made several comments of 140-characters or less about "sluts" and gay men at the gym between 2009 and 2011, according to Huffington Post.

According to Czahor's Tweet on Monday, he is #learning and #maturing.
