Veteran Hillary Clinton campaign aide Howard Wolfson has become a Fox News Channel contributor. He is expected to make his debut in that role Wednesday on the cable news channel.

Mr. Wolfson, whose fierce persona and way with words has been known to create friction with the press, was communications director and a top campaign strategist for Sen. Clinton.

He joins a stable of Fox contributors that includes former Bush White House adviser Karl Rove, also known for his strong personality and sharp tongue.

“Howard was part of the inner working circle of Sen. Clinton’s campaign and has a unique perspective on just how unconventional this election year already is,” John Moody, Fox executive VP of news editorial, said in the announcement Tuesday. “He has proven himself on key campaigns throughout the last decade and is recognized as one of the top communications and political thinkers in the Democratic Party. We look forward to benefiting from his insight during the general election campaign and beyond.”

Mr. Wolfson also is again working as a partner in the Glover Park Group, a strategic communications firm where he has worked since 2002. There he specializes in integrated campaigns, political advertising and communications and crisis management.
