YUGE: Donald Trump, Republicans Finalize Joint Fundraising Deal.

Raising money jointly with the party allows Mr. Trump to raise funds more efficiently. Instead of finding a broader base of donors to write checks of up to $2,700, he can tap a smaller set of wealthy donors for larger checks. But the joint fundraising committees are also limited in what they can transfer to his campaign and spend on his behalf.

The deal effectively raises the maximum individual donation to $449,400.
