EU reassured about US relations after 'open and frank' talks with Mike Pence

US vice president Mike Pence has reassured European Union officials about the Trump administration's stance towards the EU, according to European Council president Donald Tusk.

Mr Tusk said he and Mr Pence held "open and frank talks" aimed in part at allaying concerns about President Donald Trump's support of the EU and of European security through the Nato military alliance.
