PHOENIX - Arizona's 11 Electoral College members unanimously voted for Republican Donald Trump.
The meeting of the electors Monday at the state Capitol came as members were inundated with emails, hundreds of letters and untold numbers of calls urging them not to cast their ballots for Trump.
One of the electors, Alberto Gutierrez, said he had received more than 90,000 emails and enough letters to stack four feet tall.
All the messages called for him to get against the November vote, but that didn't change his decision.
The same pressure was being placed on Republican electors across the nation.
About 150 protesters marched around the Capitol mall in opposition to Trump, for the second day in a row,
They carried signs that said, "Stop Trump," ''Our electors should be our protectors" and "Hand picked by Putin - what could go wrong."
The electors are all Republicans because Trump won the Arizona election with 49 percent of the vote compared with Democrat Hillary Clinton's 45 percent.
They were picked by the state party.
After the official signing, the electors took a picture with Secretary of State Michelle Reagan.
Arizona's 11 members of the Electoral College had been expected to confirm the state's popular vote for the president-elect, though they were not bound by law to do so.
