Norm Coleman, a Jewish former U.S. senator, has added his name to a growing list of Republicans declaring they will not vote for Donald Trump, their party's presumptive nominee for president.

- Donald Trump calls critics of Star of David tweet 'sick people'
- Trump takes in $51 million in new campaign fundraising success
In an op-ed published by the Minneapolis Star Tribune newspaper, Coleman wrote: "I won't vote for Donald Trump because of who he isn't. He isn't a Republican. He isn't a conservative. He isn't a truth teller.".
"I also won't vote for Donald Trump because of who he is. A bigot. A misogynist. A fraud. A bully."
"When Trump refused to condemn the embrace of the Ku Klux Klan and David Duke and then tried to blame his moral failing on a faulty earpiece, it became clear that it is not in his ear where there is a problem – it is in his hear," he wrote.
"It is said that our leaders are a reflection of who we are. If we believe that, then people like Donald Trump will fall. If not, then people like Donald Trump will rise up, and like every fascist before them, will lead a nation to its doom.
"America is a great nation. We were a great nation long before Donald Trump sold us on a slogan – and we can be a great nation without Trump's false promises built on a legacy of fiction. Keep America great. Fire Donald Trump," he added.
Other leading Republican names have been declaring their objections to Trump's candidacy for months, citing his divisive rhetoric.
Jeb Bush, brother of former President George W. Bush posted on Facebook in May that he would not vote for Trump.
"In November, I will not vote for Donald Trump or Hillary Clinton," Bush wrote.
"The American Presidency is an office that goes beyond just politics. It requires of its occupant great fortitude and humility and the temperament and strong character to deal with the unexpected challenges that will inevitably impact our nation in the next four years," he added.
"Donald Trump has not demonstrated that temperament or strength of character," Bush wrote.
One of Trump's most prominent opponents is longtime columnist George Will, who left the GOP last week over Trump's presumptive nomination, saying "this is not my party."
