Heads of Aerospace Industries Association and National Manufacturers Association were in attendance

Senior executives of at least three associations met with presumptive GOP presidential nominee Donald Trump on June 9 as part of a larger conference between the candidate and several lobbyists and business leaders.

David Melcher, CEO of the Aerospace Industries Association, was among those in attendance, the association said in a news statement. National Association of Manufacturers CEO Jay Timmons was also present, according to a source with knowledge of the event. A financial industry source confirmed on background that he, too, was there.

"He spent an hour and a half to two hours with us and it was a really, really productive session," the financial industry source said, speaking on background because of an understanding with Trump not to talk about the event publicly.

The meeting took place in New York City.

"A lot of this is, we wanted to see where he's at policy-wise, and our assessment is that he's genuinely looking for tools and levers that he can use as president to get the economy moving," the source said. "We've got some ideas and I think he's open to those ideas."

Trump has said he would scrap the Dodd-Frank financial reforms, but the source said his industry does not seek a wholesale repeal.

Several news outlets reported that the New York City meeting also included Republican National Committee Chair Reince Priebus and New Jersey Gov. Chris Christie. The event, reportedly labeled the "Trump Leadership Council," was held to give representatives from various industries a chance to provide input to the candidate about the issues they faced.

In a statement, Melcher said that AIA's role is to educate elected leaders and candidates on the industry's importance to the economy and national security.

"AIA has also been in contact with the Clinton campaign regarding a similar opportunity to brief Secretary Clinton," he said.
