President Trump beat verbal jabs on Joe Biden on Friday over NATO, China and the democratic president's forerunner's comments on him as a "thump".
"I don't think I'm a bullshit," the president told reporters on the White House lawn before leaving his golf club in Bedminster, NJ.
Biden said on CNN earlier Friday that Trump is "the mob I knew all my life."
"He's the bully used to make fun when I was a kid, I stuck, and I hit him in the mouth," said Biden in response to host Chris Cuomo's question of how democratic voters can be sure that He is up to the task of taking the fight against President.
Trump also attacked Biden over China.
"We've lost our shirts with China, and now die China to make an appointment. And by the way, we take billions and billions of dollars in fees and China pays for it, not our people," he said.
"So if you look at what we've done and if you look at it, I call it Obama-Biden messy," added Trump.
In his interview on CNN, Biden also warned that NATO would be dissolved if Trump wins another office mandate.
The president has long expressed skepticism about the multinational alliance and complained that for many of its members failed to meet the objectives of defense spending.
In his prodding, NATO members' defense spending has risen since 201
"Let me say that if he wins re-election, I promise you that there will be no NATO in four years or five years," said Biden.
"What annoys me abroad is, see, the idea that we can go alone without alliances for the next 20 or 30 years is a disaster," continued Biden.
"I'm coming out of a generation where we tried to be politicians in the world. We can't go anywhere. We need allies," he said.
"He's definitely them. He embraces thugs. He embraces Kim Jong Un, who's a dew. He embraces [Russian President Vladimir] Putin, a flat dictator."
In his comments on the White House Friday Said Trump: "Tell Biden that NATO has taken the total advantage of him and President Obama. We paid for almost all of NATO."
He continued: "We protect countries, these countries must protect themselves with us. They have to make a contribution. In my first year, I raised over $ 100 billion from these countries. Biden didn't know what the hell he did, nor did President Obama. "
Trump added that" NATO is fine – but they must pay off. "
Obama and Biden" did not have a key. They were exploited by China, by NATO, by every country, "he said.
