Meet the Anti-Trump Woman funding the effort to stop Trump

Marlene Ricketts, the wife of billionaire T.D. Ameritrade founder J. Joe Ricketts, contributed $3 million to Our Principles Political Action Committee (PAC), a super PAC that blistered Trump with digital negative ads, voter guides and mailers ahead of the Iowa caucuses and the New Hampshire and South Carolina primaries. Katie Packer, who helped manage Mitt Romney's 2012 presidential campaign, runs the group.
 
Virtually all the money the committee raised in January came from Ricketts, whose family owns the Chicago Cubs.
  
Ricketts lives in Nebraska. Her son, Pete, is the state's governor.
 
Our Principles PAC has spent more than $3.5 million on its anti-Trump efforts so far.
 
On Sunday, Packer said there are no plans to retreat — despite Trump's win Saturday night in South Carolina.
 
"We will continue to shine a bright light on Trump's liberal statements and inconsistencies," Packer said in an email.

Our Principles PAC is funding that underscore Trump’s call in 2008 for Bush’s impeachment over the war in Iraq.
