WASHINGTON (AP) — The Obama administration is looking into whether a “Cuban Twitter” program secretly backed by the U.S. government contained messages that were political in nature, despite assertions from the administration that the effort was intended only to increase the flow of information in a country that heavily restricts Internet access.

State Department spokeswoman Jen Psaki said Wednesday it would be “troubling” if political messages were sent under the program. She said the program’s sponsor, the U.S. Agency for International Development, was trying to determine whether any of the messages that were sent were in fact political, as well as the timing of the messages, and whether they were drafts or were actually sent.
