Trump said it was "very inappropriate" that the U.S. is contributing to the defence of Europe when one of its richest countries is supporting a major energy project with Moscow.

"Your message is having an impact, and we are going to build on that", Mr Stoltenberg told the U.S. president over toast and orange juice, before adding: "Let me also add that a strong North Atlantic Treaty Organisation is good for Europe and it's also good for the United States".

Halep failed to carry on the momentum, and a huge forehand victor gave Hsieh the first break of the second set and a 2-1 lead. Sasnovich will next meet No. 12 seed Jelena Ostapenko who stopped the Sharapova-killer Vitalia Diatchenko 6-0, 6-4.

The increased spending predates Trump.
"The president is going to mention the fact that Europe is becoming more and more dependent on Russian Federation for their energy sources, specifically Germany with their invitation to the Nord Stream 2 pipeline", Barrasso told Fox News. On 17 May, the Wall Street Journal reported that Trump is demanding that Germany drop Nord Stream 2 as one of the conditions for a trade deal with Europe that would not include high tariffs on steel and aluminium.
