Donald Trump Kisses Son Donald Trump Jr. and Family Goodbye as He Boards Air Force One in Ireland: Photos

Donald Trump said goodbye to his family after spending the weekend together in Ireland.

The president was photographed sharing a warm farewell with son Donald Trump Jr. and other members of the Trump family before boarding Air Force One following his visit to the Emerald Isle.

Trump's trip mixed official business with family time, with several of his children and grandchildren joining him as he attended the Irish Open at his Trump International Golf Links & Hotel in Doonbeg, Co. Clare.

Trump, 80, stopped to say goodbye to his family on the tarmac before heading back to the United States.

The president, sporting a white "USA" baseball cap with his suit, was photographed chatting with the group before making his way toward Air Force One.

Donald Jr. and his wife, Bettina Anderson, were among the family members who joined the president in Ireland. Three of Donald Jr.'s children also made the overseas trip, which reportedly marked their first visit to the country.

The president appeared especially affectionate as he parted ways with his eldest son.

Trump pulled Donald Jr. in for a hug and appeared to kiss him on the cheek as his grandchildren stood nearby.

The family had spent the weekend together during Trump's two-day visit, which included diplomatic meetings in Dublin before the president traveled west to his Doonbeg resort for the Irish Open.

Donald Jr. wasn't the only familiar face on the tarmac, as several of the president's grandchildren joined the family getaway.

The younger Trumps were seen traveling alongside their dad throughout the visit, including after arriving in Dublin on Saturday, September 12.

Trump's son Eric Trump was also in Ireland and joined his father at the golf tournament in Doonbeg.

The president's delegation leaned heavily toward family and close aides, with Donald Jr., Anderson and three grandchildren among those accompanying him.

The family farewell capped off a busy trip for Trump.

During his time in Ireland, the president met with Irish President Catherine Connolly and Taoiseach Micheál Martin before heading to Doonbeg to attend the Irish Open.

Trump also drew attention for saying he would "love to see" a united Ireland, comments that quickly became one of the biggest political stories of his visit.

After mixing diplomacy with a weekend of golf and family time, Trump said his goodbyes before beginning the journey back to Washington, D.C.
