Donald Trump says he has lined up all the speakers for the 2016 Republican National Convention — and will reveal them next week.

The party's presumptive nominee tweeted Saturday that speaking slots for the upcoming convention in Cleveland are "totally filled," and there's a "long" waiting list of more speakers.


Trump indicated that a list of speakers would be released on Wednesday.

Trump previously announced a line-up of speakers including former sports stars, many of which later said they had not been contacted about speaking roles.

Earlier this week, POLITICO reached out to 50 prominent Republicans regarding their plans to attend and/or speak at the event. Few said they were interested in attending.

A story in the New York Times published Friday detailing a lack of planning and organization for the convention also revealed, via two unnamed aides, that Trump was unaware the event must take place in Cleveland — a site the Republican National Committee settled on nearly two years ago.

Trump took to Twitter on Saturday morning to reject that.

"Just read in the failing @nytimes that I was not aware 'the event had to be held in Cleveland' - a total lie. These people are sick!"
