Story highlights Major Republican donors are concerned about Donald Trump's continued wins

The Kasich campaign says they have not had anyone yet suggest that the governor should drop out

Washington (CNN) Some major Republican donors, concerned about Donald Trump's early contest wins, are looking to clear the field some more for Marco Rubio and intend in the next few days to privately urge John Kasich to drop out, according to a major GOP bundler.

Kasich told CNN's Wolf Blitzer on "The Situation Room" that he was confident about his financial position and his path to victory.

"I haven't heard from any of the special interests to get me to drop out," Kasich said Monday. "We're signing up some significant Republican fundraisers and our political organization is expanding as well."
