SAN JUAN, Puerto Rico (AP) — The adviser to Puerto Rico's most powerful female lawmaker has apologized for sending tweets to President Barack Obama that many here have deemed racist.

Heidi Wys tweeted on Thursday night that she lamented the tweets were seen as racist and that she apologizes to those offended by them. Wys said her intention was to attack a politician she doesn't believe in.

In response to the U.S. first lady's upcoming birthday, Wys had sent a tweet to Obama urging him to buy her a double-banana sundae and take her to Kenya.

Wys is the main adviser to House of Representatives President Jenniffer Gonzalez and has earned $630,000 since 2008 for her services as an administrative consultant.

Several legislators have demanded that Wys step down or that Gonzalez ask for her resignation.
