Donald Trump announced on Thursday that North Dakota Governor Doug Burgum - a wealthy former software company executive - would be his pick to head the Interior Department.
Trump was speaking on stage during a gala at his Mar-a-Lago resort when he seemed to debate whether he would spoil the surprise early, before naming Burgum.
'He's going to head the Department of Interior, and it's going to be fantastic,' a tuxedo-wearing Trump said, adding that he would make an official announcement on Friday.
'We have a big announcement and I won't tell you the exact name, I think he's an incredible person, he's got an unbelievable wife named Kathryn,' Trump said.
'So I won't tell you his name, it might be something like Burgum, he's from North Dakota. He's going to be announced tomorrow for a big position.'
