Donald Trump's been meeting with Israel's prime minister Benjamin Netanyahu in Washington. And the Trump administration has issued an ultimatum to NATO members, demanding they start increasing defence spending or Washington will "moderate its commitment" to them. Members of Mr Trump’s new government are making their first official visits to Europe this week and Mike Pence, vice president, is due to meet the head of the European Council, Donald Tusk. To find out what came out of the meeting and what the NATO issue is, Sue Dougan was joined by Josh Lowe of Newsweek.
