US President-elect Donald Trump's appointments for his second term have followed a handful of themes. Many of them are long-time loyalists, or one-time Fox News hosts - or they are part of, or connected to, his extended family.

Kimberly Guilfoyle, 55, ticks all three of those boxes. The former Fox host was nominated to be US ambassador to Greece on Tuesday.

She is a fierce defender of Trump who has worked on behalf of his presidential campaigns.

The one-time lawyer is also engaged to Donald Trump Jr, though tabloids have recently spotted the president's eldest son holding hands with another woman - making the current status of their relationship unclear.

Ms Guilfoyle was previously married to Gavin Newsom, the governor of California and a member of the rival Democratic Party.

Announcing her appointment, Trump Sr called Ms Guilfoyle a "close friend and ally".

"Her extensive experience and leadership in law, media, and politics along with her sharp intellect make her supremely qualified to represent the United States, and safeguard its interests abroad," Trump said.

"Kimberly is perfectly suited to foster strong bilateral relations with Greece, advancing our interests on issues ranging from defence cooperation to trade and economic innovation."

Writing on social media herself, Ms Guilfoyle thanked Trump for the appointment, saying she was looking forward "to delivering on the Trump agenda, supporting our Greek allies, and ushering in a new era of peace and prosperity".

Hers is one of the appointments that will require the confirmation of US senators.

Before spending more than a decade at Fox, Ms Guilfoyle was a former San Francisco and Los Angeles prosecutor.

After leaving the broadcaster, she joined the Trump campaign.

Ms Guilfoyle's appointment marks the latest in a string of appointments for one-time or current Fox hosts or contributors. They include Pete Hegseth, the president-elect's nominee for defence secretary, Trump's transportation secretary nominee who once co-hosted a Fox show, and Janette Nesheiwat, Trump's pick for surgeon general.

While the exact status of Ms Guilfoyle in the Trump family is not fully clear, she is not the first close connection who Trump has appointed to a top job.

Charles Kushner - the father-in-law of Trump's daughter Ivanka - was appointed to be ambassador to France. While Massad Boulos - the father-in-law of Trump's other daughter Tiffany - was selected to be the president-elect's senior adviser for Arab and Middle Eastern affairs.

Ms Guilfoyle and Trump's eldest son have been engaged since 2020. Neither she nor Donald Trump Jr have commented on their current relationship status in response to the latest tabloid speculation.
