"The US is our biggest trading partner and we have more than $1 trillion invested in each other's economies. We want to get formal talks moving quickly."
After his first phone call with Johnson, Trump told reporters that a bilateral deal with post-Brexit Britain could be "three to four, five times" bigger than current trade and once London is out of the European Union "we could do much more."
