On Tuesday night, Trump announced his pick for secretary of the Navy: Palm Beach businessman John Phelan. Here's what to know.

President-elect Donald Trump said Tuesday private investment manager and Republican donor John Phelan is his choice for Secretary of the U.S. Navy.

President-elect Donald Trump has chosen John Phelan, a businessman and investor with no military experience, to become the next secretary of the Navy.

While officials and defense experts said the Navy is in sore need of a disruptor, they cautioned that John Phelan's lack of experience could make it more difficult for him to realize Trump's goals.

Financier John Phelan has been tapped as Donald Trump’s nominee for the next Secretary of the Navy, according to a late Tuesday statement. Phelan is the founder of private equity firm Rugger Management LLC and previously served as the chairman and chief investment officer of the firm that oversaw the fortune of Dell Technologies founder Michael Dell.

The least qualified and most overtly political cabinet in American history continues to expand,” said army veteran Paul Rieckhoff, founder of Iraq and Afghanistan Veterans of America.

Phelan is the first service secretary pick announced by the president-elect for his second term in the White House.

John Phelan is President-elect Donald Trump's pick for secretary of the Navy, the first service leadership position that the incoming administration has announced as it prepares to put its stamp on the military.

At his Aspen home near North Star Nature Preserve on Aug. 10, financier John Phelan hosted a private fundraiser for the Trump campaign that reportedly raised $12 million. Now he is Trump's pick to be secretary of the Navy.
