Republican Sen. Ben Sasse of Nebraska wrote a lengthy Facebook post stating that he wouldn't vote for Donald Trump if he became the Republican Party's nominee for president.
Sasse, a first-term senator, criticized Trump in the post, saying the real estate mogul was focused on "dividing Americans" and talking as if he were "running for king."
"Conservatives understand that all men are created equal and made in the image of God, but also that government must be limited so that fallen men do not wield too much power," he wrote. "A presidential candidate who boasts about what he'll do during his 'reign' and refuses to condemn the KKK cannot lead a conservative movement in America."
Sasse said that instead of voting for Trump if he got the GOP nomination, he would seek a third candidate.
"If Donald Trump becomes the Republican nominee, my expectation is that I will look for some third candidate -- a conservative option, a Constitutionalist," he wrote.
Sasse recently made headlines when he said he would confirm President Barack Obama's replacement for Supreme Court Justice Antonin Scalia as long as the nominee rejected the Obama administration's approach to governing.
