The leader of the governing PNP in the Puerto Rican Senate, Roberto Arango, resigned amid a scandal over nude photos that appeared on an iPhone social-networking application for gay and bisexual men.

The news was made public by Senate President Thomas Rivera Schatz in a press release announcing that the resignation will become effective as of Wednesday.

"The circumstances that have brought about Sen. Arango's resignation, which he explains in his letter, are extremely regrettable. I believed that with the legislator's resignation we can put the matter behind us and focus on discussing subjects that are important for our people," Rivera Schatz said.

Rivera Schatz said that Sen. Larry Seilhamer will temporarily fill the position of Senate majority leader.

Several days ago the daily Primera Hora published two pictures, one of a naked man with his face partially covered by a cell phone, and another that appears to be the same person but dressed and with the caption: "Arango, is it you or not?"

The senator called it a "tall tale" being connected with the photos circulating on the Internet, though he did not deny that he was the one in the pictures.

For its part, the daily El Nuevo Dia said that the photos were posted on the gay and bisexual iPhone app Grindr.

Gov. Luis Fortuño also weighed in on the scandal and said that if the pictures that the media connect with Sen. Arango really are of a public official, that person should resign.
