Trump to May: 'Stick around'
Meanwhile Mr Trump has told out-going British Prime Minister Theresa May to "stick around" and "do this deal", as protesters gathered in London for the second day of his state visit there.
Mrs May and Mr Trump hosted a round-table business discussion on Tuesday morning, with Mr Trump saying he believes Britain can have a "very, very substantial trade deal" with the US after Brexit.
Mrs May told assembled delegates she believes in keeping markets "free and fair and open".
She said afterwards there were "huge opportunities" for Britain and the US to work together in the future.
She told Mr Trump: "It is a great partnership but I think a partnership we can take even further.
"Of course that is with a good bilateral trade deal."
Mr Trump said: "I think we will have a very, very substantial trade deal. This is something you want to do and my folks want to do."
He added to Mrs May: "Stick around. Let's do this deal."
