A number of major Republican business leaders held a conference call to solicit donations for an anti-Donald Trump super PAC.
Meg Whitman, Todd Ricketts and Paul Singer are just three business leaders who participated in the conference call with about 50 people, urging them to raise funds for the Our Principles political action committee.
The PAC was funded mostly by Ricketts' family, and started airing ads in Iowa before the state's Feb. 1 caucuses in an attempt to stop Trump from winning there.
The call was not focused on the business leaders unifying to back any particular candidate, The New York Times reported. The focus was solely on stopping Trump from getting the Republican nomination.
Whitman, who previously backed Gov. Chris Christie of New Jersey, criticized him for edorsing Trump after suspending his campaign. Whitman called the endorsement "opportunistic," especially considering Christie referred to Trump as ill-prepared for the presidency during his campaign.
A significant number of super PACs aired anti-Trump ads in the two weeks leading up to Super Tuesday, on March 1. Around 6,000 ads aired before the Super Tuesday primaries that were meant to blast the real estate mogul.
The ads symbolized a frantic effort to thwart Trump's chances at the nomination, after most of the Republican Party dismissed his actual chances for months.
"People are starting to panic," Texas A&M University political science professor Johanna Dunaway told Time. "So now, you see the efforts to try to stop his path to nomination.”
The Our Principles PAC was formed only days before the Iowa caucuses, and has spent roughly $4.4 million on ads that attempted to label Trump as a liberal. Two other conservative groups, Club For Growth and American Future Fund, have also spent millions on anti-Trump ads.
American Future Fund recently released ads that featured former students of Trump University, all of whom claimed to have been scammed and forced into debt. Trump is facing lawsuits over the issue.
"I was trumped by Trump," one ex-student said in an ad. "I was duped by the Donald."
Despite efforts from both Republicans and Democrats to bring him down, Trump's numbers have continued to improve nationally.
