If 2008 Republican presidential candidate Sen. John McCain ever gets the itch for another run at higher office, maybe the newly minted "citizen" of Palau can look outside the U.S.

The tiny South Pacific nation honored the Arizona lawmaker, who is vacationing there with his family this week, with honorary citizenship, the senator said in a Twitter post Thursday. He received the honor after the Palau National Congress invited him to speak, his office said.

McCain tweeted that it was "great to be with [the Palau Congress] today." The post included a picture of McCain seated with people who appear to be Palau politicians.

McCain also tweeted other photos from his trip, including one with Palau's president and first lady.

Palau, an English-speaking nation with a population of about 21,000, consists of several small islands within the Micronesia archipelago. The democratic nation gained its independence from the United States in 1994, but retains close ties with the U.S.

McCain also visited Palau with his family in 2003.
