Donald Trump cancelled his Saturday morning speech at the Conservative Political Action Conference in suburban Washington, D.C., the conference announced on Twitter on Friday.

Very disappointed @realDonaldTrump has decided at the last minute to drop out of #CPAC — his choice sends a clear message to conservatives. — CPAC (@CPAC) March 4, 2016

The Trump campaign confirmed in a Friday statement that he will not speak at the conference, and will instead hold a rally in Kansas:

The Donald J. Trump for President Campaign has just announced it will be in Witchita, Kanasas for a major rally on Saturday prior to Caucus. He will also be speaking at the Kansas Caucus and then departing for Orlando, Florida and a crowd of approximately 20,000 people or more. Because of this, he will not be able to speak at CPAC as he has done for many consecutive years. Mr. Trump would like to thank Matt Schlapp and all of the executives at CPAC and looks forward to returning to next year, hopefully as President of the United States.

The conference typically draws in the Republican base, and all of the other remaining Republican presidential candidates are scheduled to speak at the conference either on Friday or Saturday.
