Former Florida Gov. Jeb Bush and Wisconsin Gov. Scott Walker, two potential 2016 presidential candidates, plan to speak to Republican donors at the national party's spring retreat in Boca Raton, Fla., in March, a senior Republican official told Fox News. 

Other potential 2016 candidates have been invited to the Republican National Committee meeting but have yet to confirm. 

The meeting of roughly 60 major donors will be held at the Waldorf Astoria hotel in southwest Florida. The money raised will go to the Republican Majority Fund -- a fund that supports Republican senatorial candidates. Other figures set to speak at the RNC retreat include newly elected Republican Sens. Cory Gardner of Colorado and Thom Tillis of North Carolina. 

For possible presidential candidates, it is an opportunity to court donors for their own potential bids. 

Bush was invited to the RNC winter retreat in San Diego, Calif., earlier this month but did not attend. Former Republican presidential nominee Mitt Romney, former Gov. Rick Perry of Texas, Walker and others spoke at the meeting.
