President Donald Trump announced one final $1 trillion deal on the last day of his Middle East trip and then said he was headed home to see his new grandson.

Trump's daughter Tiffany gave birth to a baby boy - Alexander Trump Boulos - on Thursday. It's her first child and the president's 11th grandbaby.

'It's been a tremendous time. Now it's time to go back home. My daughter had a baby. I'm going to go back home and see that little baby,' Trump said at a business roundtable in Abu Dhabi.

'I probably should have left yesterday,' he conceded. 'But I couldn't disappoint you,' he told Crown Prince Khaled Bin Mohamed Bin Zayed Al Nahyan. 'Your father would have been extremely upset with me, and you would have been more upset.'

With the announcement Trump confirmed he would not be headed to Turkey for talks on a Russia-Ukraine peace deal. The president had dangled the possibility of a drop-in but Russian President Vladimir Putin decided not to go to Istanbul to meet with Ukrainian President Volodymyr Zelensky.
