美国大选最后一场辩论（实时直播）：特朗普和拜登就奥巴马遗留的移民问题激烈辩论

特朗普说，他的政府正在“尽力”寻找与父母分居后无法找到父母的545个孩子。但是，总统还说，有些孩子是被“土狼”和“卡特尔”带到美国的。

然后，他转而说奥巴马政府在拘留中心建立了许多移民的拘留所。

特朗普说：“他们在某家报纸上有一张照片，里面有这些可怕的笼子的照片。他们说看这些笼子。特朗普总统建造了它们。” “然后确定他们是在2014年建造的。就是他。他们建造了笼子。”

拜登在激烈的回应中强调，孩子们与父母一起来到美国。

拜登说：““土狼”没有把他们带过来。他们的父母和他们在一起。他们与父母分离，这使我们成为笑柄，并且违反了关于我们作为一个国家的身份的每一个观念。

韦尔克问奥巴马政府未能进行移民改革的问题。

拜登说，花了太长时间才能制定正确的政策。

他说：“完成它花费了太长时间。完成它花费了太长时间。” “我将担任美国总统，而不是美国副总统。事实是，我已经非常清楚地表明，我将在100天之内向美国国会发送获得公民身份的途径1100万无证件人员以及所有所谓的梦想家，即DACA的孩子，他们将立即再次获得认证，可以留在该国并踏上成为公民的道路。”

特朗普回应说，拜登“已经有八年时间去做他说要做的事情了”。

然后，拜登和特朗普就接发政策进行了反复讨论。

'We're trying very hard' to find parents of 545 children: Trump
Trump said his administration is "trying very hard" to locate the 545 children whose parents can't be located after being separated from their parents. However, the president also said that some of the children were brought to the U.S. by "coyotes" and "cartels."

He then pivoted to say that the Obama administration built the detention centers where many migrants are held.

"They had a picture in a certain newspaper, there was a picture of these horrible cages. They said look at these cages. President Trump built them," Trump said. "Then it was determined they were built in 2014. That was him. They built cages."

In a fiery response, Biden emphasized that the children came to the U.S. with their parents.

"Coyotes didn't bring them over, Biden said. "Their parents were with them. They got separated from their parents, and it makes us a laughingstock and violates every notion of who we are as a nation.

Welker asked about the Obama administration's failure to deliver on immigration reform. Biden said that it took too long to get the policy correct.

"It took too long to get it right. Took too long to get it right," he said. "I will be president of the United States, not vice president of the United States. And the fact is, I've made it very clear, within 100 days, I going to send to the United States Congress a pathway to citizenship for over 11 million undocumented people and all of those so-called dreamers, those DACA kids, they are going to be immediately certified again to be able to stay in this country and put on a path to citizenship."

Trump responded that Biden "had eight years to do what he said he was going to do."

Biden and Trump then went back and forth over the catch-and-release policy.
