Nebraska Governor Pete Ricketts, whose family has spent at least $5.5 million bankrolling the anti-Trump Our Principles PAC, will endorse Donald Trump at a campaign rally in Omaha today. The governor had been expected to endorse Ted Cruz.

Yesterday morning, the New York Times reported on a super-PAC plan submitted to Joe Ricketts, founder of TD Ameritrade and owner of the Chicago Cubs. Entitled, "The Defeat of Barack Hussein Obama: The Ricketts Plan to End His Spending for Good," it proposed a $10 million series of ads tying Obama to Reverend Jeremiah Wright. By early afternoon, Ricketts had abandoned the plan outright.

At a press conference in Jacksonville today, Mitt Romney said he rejected a plan presented by GOP strategists to a Super PAC funded by Cubs-owning billionaire Joe Ricketts aimed at "defeating" President Obama by rehashing his ties to controversial reverend Jeremiah Wright.
