When Donald Trump ran into trouble on convention delegates, his son Eric sprung into action, dialing delegates all over the country to lock down support for his father.

During Wednesday’s Republican National Convention speeches, the middle Trump son will give his most high-profile comments to date, but he has been a close confidant and advisor behind the scenes for months.

“Everything we’ve done, we’ve done together as a family,” Eric told TIME recently. “We’re learning together.”

Eric, 32, is the youngest of Trump’s children from his first wife. Along with his older brother Donald Jr. and sister Ivanka, he has been part of Trump’s inner circle for months.

Outside politics, Eric manages Trump’s golf courses and construction projects. He is overseeing the $290 million renovation of Turnberry golf course in Scotland that Trump visited last month.

Earlier this month, Eric suggested that his sister Ivanka would make a great vice president.
