Turkey is doing an enormous amount in the refugee question, but it can't continue to pay for everything by itself. That is why we have to talk to Turkey about money.

CDU head Angela Merkel has tried for years to serve two sides: the conservative side by holding up her CDU party membership. But then at the same time she acts as though she were also a Social Democrat. I don't have this hydra-headed nature. In the end, people will vote for the Social Democratic original.

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.

Would I sacrifice a friendship to take a step forward in my political career? Thus far in my political career, I have been spared from having to make such a decision, thank God. And I can't imagine what it must be like.

When it comes to climate protection, the whole world will have to pay the price. But if Donald Trump intends to conclude a trade agreement with the EU, he will have to abide by our climate standards. In any case, waiving climate protection does not make American products more competitive.

I know people's problems: the problems of those who work hard, who must slave away. The couples who have two incomes but who can nevertheless barely cover their rent. The people who get stuck in traffic on their way to work. The people who have to wait in vain for a train to come just as they are supposed to be picking up their children from daycare. I can say with a clear conscience to those people: I understand your problems. And I will do all I can to decrease them.

I am strictly against making cuts in the current budgetary period for things such as research funding and investments as a reaction to Brexit. I think that we can do an excellent job of explaining this to the German people.
