(CNSNews.com) - On his way into the United Nations General Assembly on Tuesday, President Trump stopped to answer a few shouted questions from reporters.

One of them asked him why he (temporarily) withheld U.S. military aid from Ukraine. Another reporter asked him about the new impetus for impeachment.

"As far as withholding funds," Trump responded:

Those funds were paid. They were fully paid, but my complaint has always been -- and I'll withhold again and I'll continue to withhold until such time as Europe and other nations contribute to Ukraine because they're not doing it. Just the United States. We're putting up the bulk of the money. And I'm asking, why is that? And I want Europe -- and it's always been this and everybody knows it -- every single reporter knows it, everybody in the administration knows that what I want and I insist on it, is that Europe has to put up money for Ukraine also. Why is it only the United States putting up the money? And by the way, we paid that money. But I always ask, why aren't other countries in Europe especially putting up money for Ukraine?

On calls for impeachment, Trump repeated that it's "ridiculous," another "witch hunt."

I'm leading in the polls. They have no idea how they stop me. The only way they can try is through impeachment. This has never happened to a president before. There has never been a thing like this before. It's nonsense and when you see the call, when you see the read-out of the call (with the Ukraine president), which I assume you'll see at some point, you'll understand. That call was perfect. It couldn't have been nicer. And even the Ukrainian government put out a statement that that was a perfect call. There was no pressure put on them whatsoever. But there was pressure put on with respect to Joe Biden -- what Joe Biden did for his son. That's something they should be looking at.

Biden's troubled son Hunter landed a lucrative job with a Ukrainian state gas company while his father was serving as vice president. Despite that apparent conflict of interest, Joe Biden in 2016 forced the Ukraine government to fire a prosecutor who was looking into corruption.
