Donald Trump has decided not to attend the Conservative Political Action Conference, according to the group's Twitter account.
Trump was scheduled to speak Saturday morning at the gathering of conservative activists in suburban Maryland. The four other GOP presidential contenders are still slated to attend.
The American Conservative Union, which holds CPAC, wrote: "Very disappointed @realDonaldTrump has decided at the last minute to drop out of #CPAC -- his choice sends a clear message to conservatives."
Trump's campaign says in a statement that he will be holding a rally on Saturday in Kansas, followed by one in Orlando, and therefore will not be able to attend the conference.
The statement says Trump looks forward to attending next year, "hopefully as president of the United States."
