Conservative radio host Mark Levin follows Rush Limbaugh, Karl Rove and Supreme Court Justice Clarence Thomas as keynote speaker for Hillsdale College's annual Churchill Dinner.

Levin hosts a nationally syndicated talk show on New York's WABC-AM. He's the author of the 2009 best-seller "Liberty and Tyranny: A Conservative Manifesto."

This year's Churchill Dinner is Thursday at the Renaissance Mayflower Hotel in Washington.

The Hillsdale, Mich., school holds the invitation-only event in the nation's capital to honor World War II British leader Winston Churchill.

Limbaugh spoke last year and Thomas in 2007. Other past speakers include President George W. Bush adviser Rove and ex-U.S. Sen. Jesse Helms of North Carolina.
