For the first time in its 126-year history, the Arizona Republic has endorsed a Democratic candidate for president.
The paper's editorial board said Hillary Clinton is "the only choice to move America ahead."
"Since The Arizona Republic began publication in 1890, we have never endorsed a Democrat over a Republican for president. Never. This reflects a deep philosophical appreciation for conservative ideals and Republican principles," the paper's editorial board wrote. "This year is different."
The editorial said Clinton's temperament and experience prepares her for office, while it questioned Trump for not releasing his tax returns, asking "whose hand do you want on the nuclear button?"
