WASHINGTON - US President Donald Trump is considering a new order to replace his soon-to-expire travel ban on people from six Muslim-majority countries that would be tailored on a country-by-country basis to protect the United States from attacks, US officials said Friday.With the current ban on people from Iran, Libya, Somalia, Sudan, Syria and Yemen due to expire Sunday, Trump was given recommendations by Elaine Duke, the acting homeland security secretary, but has not yet made a decision on the details of any new order, the officials told reporters.Miles Taylor, counselor to Duke, said she recommended to Trump "actions that are tough and that are tailored, including travel restrictions and enhanced screening for certain countries." Taylor declined to say which or how many countries would be targeted, including the status of the six countries covered by the current ban.White House spokesman Raj Shah said that while "we can't get into decision-making," the next step will be a presidential proclamation setting out the new policy. He declined to say when that would come, including whether Trump would act before the existing ban expires.The American Civil Liberties Union, the rights group that mounted one of the legal challenges to the March order, expressed skepticism about Trump's forthcoming action."This looks to be the Trump administration's third try to make good on an unconstitutional campaign promise to ban Muslims from the United States," ACLU Executive Director Anthony Romero said.Trump's six-nation travel ban was laid out in a March 6 executive order that was blocked by federal courts before being allowed to go into effect with some limits by the US Supreme Court in June. Under the recommendations Trump is weighing, there would be restrictions on US entry that differ by nation, based on cooperation with American security mandates, the threat the United States believes each country presents and other variables, Taylor said. He did not specify the nature of the restrictions, but said that after being imposed they could be lifted "if conditions change."The legal question of whether the existing ban discriminates against Muslims in violation of the US Constitution, as lower courts previously ruled, will be argued before the Supreme Court on Oct. 10. Officials declined to say how the proposed change in policy could affect the upcoming Supreme Court case.The March travel ban and an earlier January one that targeted the same six countries as well as Iraq are some of the most controversial actions taken by Trump since assuming office in January.Critics have called the policy an unlawful "Muslim ban," accusing the Republican president of discriminating against Muslims in violation of constitutional guarantees of religious liberty and equal protection under the law, breaking existing US immigration law, and stoking religious hatred.Trump, who has promised that "radical Islamic terrorism" will be "eradicated," wrote on Twitter on Sept. 15: "The travel ban into the United States should be far larger, tougher and more specific-but stupidly, that would not be politically correct!"WORLDWIDE REVIEWThe expiring ban blocked entry into the United States by people from the six countries for 90 days and locked out most aspiring refugees for 120 days to give Trump's administration time to conduct a worldwide review of US vetting procedures for foreign visitors. The existing refugee ban expires on Oct. 24.Taylor said American officials in July notified every foreign government of requirements for the minimum cooperation the United States needs to validate traveler identities to ensure they do not represent a national security threat. Those countries were given 50 days to respond. People from countries that did not meet the requirements may not be allowed to enter the United States or may face other travel restrictions, Taylor said. Most countries met those requirements or agreed to work toward meeting them, Taylor added."At the end of the day, some countries were still unable or, worse yet, deliberately unwilling to comply with the new baseline that we laid out," Taylor said.Trump, who promised as a candidate to impose "a total and complete shutdown of Muslims entering the United States," has said the soon-to-expire ban was needed to protect the United States from terrorism."We need to know who is coming into our country," Taylor said. "We should be able to validate their identities and we should be able to confirm that our foreign partners do not have information suggesting such individuals may represent a threat to the United States."While Trump's January and March orders were quickly blocked by federal courts, the expected new restrictions might be harder to challenge because they are the product of a worldwide review process examining vetting procedures of foreign countries, legal experts said.
