MINNEAPOLIS — GOP presidential candidate Newt Gingrich and his wife Callista were hit with glittery confetti by a protester Tuesday during the couple's appearance at a book-signing.

The man approached the Gingriches during the signing at a downtown Minneapolis hotel, dumped a cracker box full of colorful confetti on the pair and said, "Feel the rainbow, Newt! Stop the hate! Stop anti-gay politics!"

Two Associated Press reporters witnessed the event. The man was quickly pushed out of the room.
