In an interview with CNN’s Jake Tapper, Trump said while he likes rival Republican Ben Carson, the former neurosurgeon does not have the chops for negotiating with foreign powers. He said Carson is weak on both trade and immigration. Speaking on October 23, Trump emphasized that he is a “counter-puncher” who goes into action when other candidates attack him. "I like Ben, but he cannot do with trade like I do," Trump said. "He can't do with a lot of things like I do, so we'll just have to see what happens." Trump said he worries that Carson is "just not going to be able to do deals with China, to be able to do deals with Japan." In the past, Trump has said that Carson lacks the energy necessary to serve as president.
Trump fiercely critized Carson on immigration. He said of Carson, “He's very, very weak on immigration and I'm very strong on immigration," Trump said. "Ben Carson is very, very weak on immigration. He believes in amnesty strongly. He believes in citizenship. He's going to give citizenship to people who are here illegally -- you can't do that."
While has said he supports guest worker status for undocumented immigrants if they report their presence in the country. Carson has forcefully denied that he is offering amnesty, even while his policy may contemplate the granting of citizenship for guest-workers residing in the U.S.
Speaking on CBS last month, Carson said "We have to recognize that we can't just round them up, but we can give them an opportunity to register."
"I would give them an opportunity to become guest workers -- not citizens, not voting people, not people who get goodies,” said Carson in September. “I think that would be a fair way to do it. In terms of them becoming citizens later on down the road if they've done things the right way, we the American people will decide what the criteria for that ought to be."
