It was clear to me that the White House's solemn atmosphere would not civilize Trump. But the merciless nepotism with which he conducts politics, in which he places himself and his family above the law, I wouldn't have considered that possible. And on top of that there is this reduction of complex political decisions to 140 characters. When it comes to a U.S. president, I consider the reduction of politics to a tweet to be truly dangerous. Trump is a risk to his country and the entire world.

Without new money, salaries won't be paid, the health system will stop functioning, the power network and public transport will break down, and they won't be able to import vital goods because nobody can pay.

I take note of the fact that there are a lot of people who appreciate what I do as parliament president, not just within my Social Democratic party group, but also among the conservatives.

Trump believes politics is a staged fight. But it is not. Still, clear words are sometimes needed in politics. In that sense, I believe I am better than Mrs. Merkel.

Trump has a clear goal: the division of Europe and the destruction of the European domestic market. The fact that Brexit propagandist Nigel Farage was the first European he received in his tower speaks volumes. That is why we must strengthen the European domestic market and work even more closely together in Europe. That is absolutely compulsory for Germany.

Donald Trump must be taken seriously. He is fulfilling his dangerous campaign promises.
