Republican officials say Donald Trump will address the party's Lincoln Day dinner as part of his first foray into Iowa as a possible presidential contender.
The New York billionaire and reality TV figure has already announced plans to visit New Hampshire in June.
Iowa Republican Party Chairman Matt Strawn says Trump will speak June 10 in Des Moines.
Strawn says the Iowa party invited Trump so he could introduce himself to Iowa Republicans. He noted Trump's success as an "entrepreneur and job creator."
Trump has said he will decide by June whether to seek the Republican presidential nomination.
