Republicans who don’t support their party’s presumptive presidential nominee, Donald TrumpDonald John TrumpWhite House counsel called Trump 'King Kong' behind his back: report Trump stays out of Arizona's ugly and costly GOP fight Trump claims he instructed White House counsel to cooperate with Mueller MORE, are making plans to raise money for staff and possibly a legal defense fund, The Washington Post reported Sunday night. 

The group calling itself “Free the Delegates” now has several hundred Republican delegates and alternates counting themselves as members. 

The group is led by Republican National Convention delegates hoping to block Trump from receiving the nomination at the convention next month. They want to change the rules so they are not forced to vote in line with the results of their state primaries or caucuses. 

On Saturday, Trump accused former GOP presidential candidate Jeb Bush of mounting a convention coup against him after reports emerged about Republican delegates looking for ways to avoid voting for him.

But leaders of Free the Delegates insist that they are not working on behalf of any of Trump's former opponents.
