It's a billionaire feud for the ages. Notorious instigator of Twitter feuds and GOP presidential candidate Donald Trump has called out the Ricketts family on Twitter for opposing his candidacy. Marlene Ricketts, one of the cofounders of TD Ameritrade and a major Republican donor, gave $3 million to anti-Trump PAC Our Principles. Trump claims the family (of course, he misspelled their name in the tweet) has "a lot to hide." We don't expect to see him at Wrigley Field anytime soon. [Politico]

Losing to the Minnesota Wild 6-1 in the NHL Winter Classic Sunday was an embarrassing loss for the Chicago Blackhawks. Despite the team's extremely strong season, losses like that are troubling some observers, who say the team is showing an inconsistency that wasn't there in past seasons. [Sun-Times]
