WASHINGTON (AP) — Conservative columnist George Will has parted ways with the Republican Party, changing his voter registration to "unaffiliated" because of the GOP's support of Donald Trump.

Will told The Washington Post that he made the change several weeks ago. The news site PJ Media reports that Will discussed his decision during an event Friday for the conservative group the Federalist Society.

Will isn't saying whom he will support for president. He has been criticizing the billionaire businessman for months in his column for the Post and, in doing so, has drawn Trump's scorn.

Recently, Will wrote a column in which he urged Republican donors to "save their party by not aiding its nominee."

Will received a Pulitzer Prize for commentary in 1977 and has been a leading conservative voice for decades.
