Syndicated columnist and Fox News contributor George Will has left the Republican Party due to Donald Trump's presumptive nomination for president.
Will, whose column is published by The Washington Post, told that paper Saturday that he changed his Maryland voter registration from Republican to "unaffiliated" earlier this month after House Speaker Paul Ryan, R-Wis., said he would vote for the real estate mogul.
The website PJ Media reported that Will discussed his decision during an event Friday for the conservative group the Federalist Society.
"This is not my party," Will said in a speech.
Will has been a persistent critic of Trump and recently wrote a column urging Republican donors to "save their party by not aiding its nominee."
PJ Media reported that Will acknowledged Friday that it was a "little too late" to draft an alternative candidate to Trump, but told GOP voters to "make sure [Trump] loses. Grit [your] teeth for four years and win the White House."
Will told the Post he did not know who he would support for president, saying "I just know who I won't be voting for."
Will will be part of the panel on this week's edition of "Fox News Sunday".
