| The United States is a generous receiver of immigrants,as every year,it will accept immigrants from all over the world.Therefore,immigration issue is also one of the hot topics in American society.After Trump took office,he took tough measures to deal with the immigration issues and established a number of immigration policies one after another.In particular,he spent a lot of money to build a "border wall" on the US-Mexico border to block illegal immigrants from entering the country.On the grounds of protecting national security,Trump issued a "Muslim ban" to prohibit citizens from Iraq,Syria,Iran,Sudan,Somalia,Yemen and Libya from entering the United States,what’s more,he adopted a "family separation policy" to forcibly separate immigrant families,and so on.These immigration policies were resisted and protested by many state governments.During the Trump administration,the contradictions between the federal government and the state governments have deepened,the relationship between the federal government and the state governments on the immigration issue has become tense,and the power competition between the two on the immigration issue has become more intense.American federalism,the world’s largest democratic pilot,is developing in an unbalanced direction.During the Trump administration,the federal government has become more and more powerful on the immigration issue,while the state governments have less speaking right in immigration policy.The power conflict between the two has deeply affected the development of American federalism,and the federal government has further expanded its power. |
