When you earn six figures working for a top government official, it’s wise to keep your Twitter tongue in check. Heidi Anne Wys didn’t, so now people are demanding that the adviser to Puerto Rican House President Jennifer Gonzalez be fired.

Responding to a birthday picture that President Obama posted of his wife, Wys tweeted: “Who cares? Take her to Burger King, buy her a sundae with double banana, take her to your homeland, Kenya!” She penned other anti-Obama tweets before that, including one that read: “Wah! Wah! I feel like vomiting! Dinner with a guy borned in Kenya and claims he was borned in Hawaii!”

U.S. Rep. Luis Gutierrez, an Illinois Democrat of Puerto Rican ancestry, demanded that Wys be fired. “Sentiments like this simply cannot be tolerated, and the Puerto Rican leaders responsible for her employment should act without hesitation.”

Gonzalez decried her aide’s tweets but did not fire her. “The expressions disseminated are not acceptable, do not represent my sentiments and are the exclusive responsibility of those who wrote them,” Gonzalez said. Wys apologized for the tweets.)
