Bill Murray crashes White House briefing to talk Cubs

(TMZ)

Bill Murray made a surprise appearance in the White House's press briefing room Friday to talk about his favorite pastime -- the Chicago Cubs.

Rocking a Cubs pullover, Murray  downplayed Dodgers ace Clayton Kershaw and hyped up the Cubs as they return to Wrigley Field with a 3-2 lead in the NLCS.

Notoriously known as a die-hard Cubbies fan, Murray is a frequent attendee at Wrigley Field and one of the North Siders' most outspoken celebrity supporters.
