A Giuliani is finally joining the Trump administration.

President Donald Trump has brought on Andrew Giuliani, the son of former New York City Mayor Rudy Giuliani, to work in the Office of Public Liaison and Intergovernmental Affairs, two sources familiar with the hire told POLITICO.

In his new post, Andrew Giuliani, who once dreamed of becoming a professional golfer, helped organize the Patriots’ upcoming visit to the White House after their come-from-behind Super Bowl victory, and also assisted First Lady Melania Trump’s staff during Trump’s speech before a joint session of Congress last week. The younger Giuliani has known the Trump family for years.

A White House spokeswoman did not immediately respond to a request for comment.

Andrew Giuliani’s hire comes as the administration belatedly has started to fill in lower- and mid-level slots in that office — a relief to outside groups who have struggled to communicate with an overwhelmed and understaffed White House.

Rudy Giuliani, one of Trump’s earliest and most ardent supporters, was briefly in the running for secretary of state, before withdrawing his name from consideration for a cabinet-level post. The former mayor, who is the CEO of an international consulting firm Giuliani Partners, was announced during the presidential transition as an adviser to Trump on cybersecurity. He has also credited himself with being the architect of Trump’s “Muslim ban.”

Politics has split the Giuliani children. Last summer, POLITICO reported that the former mayor’s daughter, Caroline, was voting for and publicly supporting Hillary Clinton while her father served as a top Trump surrogate and a headliner at the Republican National Convention.

Andrew Giuliani is the son of the former mayor and his ex-wife, Donna Hanover. The political scion had hoped for a career as a professional golfer, and made headlines in 2008 when he sued Duke University for cutting him from the varsity golf team after he threw an apple at a teammate and threw and broke a golf club in a parking lot, according to the lawsuit. The suit was eventually dismissed.

Andrew Giuliani’s first star turn came in 1994, as his father was sworn in as mayor of New York City: as a kid, he upstaged his father by repeating parts of the oath of office along with him — and then blowing kisses, yawning, and clowning around on stage while his father delivered his inaugural address. At one point, he pushed over a pitcher of cold water that ran down his father’s leg. The shenanigans were lampooned on “Saturday Night Live,” where Andrew Giuliani was played by comedian Chris Farley.
