Hunter Biden, the scandal-hit son of US President Joe Biden, appears to have stepped out of the shadows to join his dad on a historic visit to Northern Ireland.
The president's son has been under federal investigation in recent years for tax fraud and alleged unethical relationships with foreign governments - including China and Ukraine.
During the presidential campaign, opponents brought up Hunter Biden's past - scrutinising his drug use and business dealings - in an attempt to weaken President Biden's chances of taking the White House.
As a result, Hunter Biden kept a pretty low profile during much of the campaign and early months of his father's presidency. But things have changed recently, with the president's only surviving son appearing to come out of the shadows and being a regular presence at more White House events.
He has even accompanied his father on a historic trip to Northern Ireland on the anniversary of the Good Friday Agreement.
The pair were spotted boarding Air Force One on April 11 to fly to Northern Ireland along with President Biden's sister Valerie Biden.
And during a speech the 80-year-old president gave in Dundalk, near the border of Ireland and Northern Ireland, he told his son to "stand up", saying he was "proud" of him.

It comes after a number of struggles and scandals which the US president's surviving son has endured over the years.
Childhood of tragedy
Hunter Biden was born in Wilmington, Delaware, in 1970 and was the child of President Biden and his first wife Neila. But when he was just two years old, in DEecember 1971, just a week before Christmas and less than six weeks after his dad's election to the US Senate, a truck ploughed into the family car, killing his mother and baby sister Naomi.
Hunter was left with a fractured skull, while older brother Beau suffered a broken leg. Mr Biden ended up taking his oath of office from their hospital room.
He went on to attend Georgetown University and Yale Law School, graduating in 1996. He met his first wife, Katheleen Buhle, a lawyer, while part of the Jsuit Volunteer Corps - a Catholic group that volunteers to serve marginalised communities.
The pair married in 1993 and had three children together - Naomi, Finnegan and Maisy. However, the pair split in 2017.
Storied history of drug abuse
Hunter began drinking young by US standards, as a teenager, and even confessed to using cocaine while at college.
As a result of his substance abuse issues, he has been in and out of rehab over the years.
In 2013, he signed up for the US Navy Reserves, taking the oath of office before his father, who was vice-president at the time, in a White House ceremony.
However, on his first day at the base, he tested positive for cocaine use and was discharged - something he later said he was "embarrassed" by.
After his older brother Beau died of brain cancer in 2015, it's said he began to drink excessively. There are even reports that he sometimes only left the house to buy vodka.
Daughter Naomi once wrote on Twitter: "He and Beau were one. One heart, one soul, one mind."
During their divorce filing in 2017, Kathleen Buhle accused him of "spending extravagantly on his own interests (including drugs, alcohol, prostitutes, strip clubs, and gifts for women with whome he has sexual relations) while leaving the family with no funds to pay legitimate bills".
A 2019 DNA test proved Hunter Biden to be the "biological and legal father" of a child born to an exotic dancer, Lunden Alexis Roberts.
In a 2021 memoir, Beautiful Things, Hunter confessed his infidelity was the final straw in his marriage. He claimed he had "no recollection" of the encounter with Roberts, but has settled a paternity suit and pays child support.
Speaking out about his struggle with addiction in 2019, Hunter said: "You don't get rid of it. You figure out how to deal with it."
One of the ways he was helped to deal with it was by support from his family, who he credits in his memoir for his survival.
Family and business conflicts
With his dad running for president, a whole host of Hunter Biden's former business dealings came under scrutiny.
There were concerns raised about a Washington lobbying practice opened by Hunter in the early 200s, when he was still receiving consulting fees from MBNA, which reportedly saw him making connections with "clients with interests that overlapped with [his dad's] committee assignments and leglislative priorities".
In 2006, as then Senator Biden was set to re-assume chairmanship of the Senate's Foreign Relations Committee, HUnter and another relative purchard a hedge fund group, Paradign Global Advisors.
Their tenure at the hedge fund continued through Biden's 2008 run for president, as well as his selection as Barack Obama's vice-president.
It was during this time that the fund was connected with a number of alleged criminal frauds. These included a Texas financier convicted of running one of the largest Ponzi schemes reocrded in the country's history. The Bidens denied any wrongdoing and faced no charges, liquidating the fund in 2010 and returning money to investors.
