The president’s ban on the constitutionality of travel from parts of the Muslim world, recently blocked by federal judges in Hawaii and Maryland, has caused complex problems, and rational people may differ. However, it is not controversial that the judiciary’s ability to determine its constitutionality is beyond the control of the government’s administrative department. Constitutionalists think that the constitution is the main protector against authoritarianism. In order to safeguard democracy, we must limit democracy. The Supreme Court still has certain restrictions on the president. They can prevent the president from exercising too much power.
Trump proposed a new travel ban that explicitly prohibits travelers from seven countries from entering the United States, including Iran, Libya, Syria, Yemen, Somalia, Chad, and North Korea. Not long ago, the Supreme Court suddenly cancelled the verbal argument for President Trump’s travel ban, which symbolized their refusal to recognize the legitimacy of the decree. This is the judicual branch's limitation on the executive branch, which needs to be endorsed by the Supreme Court before a decree from the president passes. Therefore, the Supreme Court has the right to refuse to recognize or pass this decree in order to limit the power of the President.
The Senate questioned the President’s right to control nuclear weapons, and Congress formally considered amending the law to allow the President of the United States to launch nuclear weapons. Because of North Korea’s constant emergence of nuclear threats and provocations, Trump began to demand the right to control nuclear weapons, giving him the ability to retaliate. The attitude of the Congress did not show opposition to the presidential power, but the Senate questioned whether the presidential power would be too large. This is a limitation of the legislative branch to the executive branch. The Senate has the power to reject the president’s arrangement.
The Supreme Court rejected Trump's bill to cancel the DACA. This will temporarily protect many young migrants from deportation. Their identities can be retained for another two years, during which time they can seek employment opportunities. This move means that immigrants are often referred to as "dreamers" unless Congress takes action to make it permanent. This is a judicial branch ‘s restriction for the executive branch. The Supreme Court can veto the President’s bill.
