(CNN) – Former Florida Governor Jeb Bush spoke about foreign policy and the economic importance of immigration reform to a group of some of the most prominent Republican fund-raisers Thursday evening in Las Vegas, several attendees told CNN. Bush addressed a private, VIP dinner of major supporters of the Republican Jewish Coalition kicking off the group's spring meeting.
"He was passionate on the economic importance of immigration reform," an attendee told CNN. Bush has repeatedly pushed for action on immigration in the last couple of years.

During the question and answer session one person told Bush he should run for President in 2016. He said "I'm going to ignore that one," according to one attendee. He turned it aside with a smile saying he had not decided and then pivoted to what policies were needed in the country, according to a separate source. Bush has said publicly he has not made his mind up about whether to seek the GOP nomination and will make a decision by the end of the year.
Some Republican fund-raisers before the event had told CNN Bush's decision to speak was significant and his address was seen as a key test. One source said Bush's address was well-received. Bush is well-known among many of these donors because of his two terms as Florida governor as well as because of the relationships built by his father and brother while they were in the White House.
About 60-70 people attended the dinner which was held in a large, private airport hangar used by Republican mega-donor and Nevada casino owner Sheldon Adelson, who hosted the event along with his wife. Adelson is one of the RJC's most prominent backers and one of the richest men in the world. Adelson did not speak at the dinner.
The sources asked not to be identified further because the event was closed to the press.
Several other possible contenders for the Republican presidential nomination – New Jersey Gov. Chris Christie, Ohio Gov. John Kasich and Wisconsin Gov. Scott Walker will speak Saturday at the event as they hope to build some support if they decide to run.
