Trump always welcome, but Poland's goals achieved - president's aide

Polish President Andrzej Duda's invitation for US President Donald Trump to visit Poland is open, but Warsaw has already achieved all the results it wanted to see in bilateral relations for this year, Duda's chief aide said on Friday. The two presidents had had two tasks to complete this year, namely the visa-free travel and boosting the US military presence in Poland, both of which have been achieved, Krzysztof Szczerski told Polish Radio Three.
