Controversy over President Barack Obama's eligibility to be president surfaced anew Monday during a ceremony to record Arizona's Electoral College votes for president.

All 11 Arizona electors cast their votes for defeated Republican nominee Mitt Romney, who won the state's popular vote.

Arizona Republican Party Chairman Tom Morrisey and two other Electoral College members spoke up during the ceremony to voice doubts about Obama's eligibility as a native-born U.S. citizen.

Hawaii officials have certified that Obama was born in that state.

Gov. Jan Brewer criticized the Electoral College system shortly after the November election, saying Arizona is left out of much of the campaign because candidates focus on the states where they can capture needed electoral votes.

Arizona has voted strongly Republican in presidential races in all but one of the last nine elections.

Changing the Electoral College system would require a constitutional amendment.
