>> This is what democracy looks like.>> It sparked chaos at airports, widespread demonstrations, and a blizzard of court actions. And now President Donald Trump's controversial travel band targeting people from several Muslim majority countries has its day before the US Supreme Court. The Court's nine justices on Wednesday hearing a challenge to the ban.
>> It's big stuff.>> Trump's policy, unveiled a week after he entered the White House and revised twice, blocks entry into the US of most people from Iran, Libya, Somalia, Syria and Yemen. Warren Turley is on the story.>> The challenges led by the state of Hawaii, which says that the Administration has violated the law in several ways.
One of which is that they have violated the US Constitution, which restricts discrimination by the government on the basis of religion. And they say this is effectively a Muslim ban, and therefore it's discriminatory.>> The plaintiffs say it's motivated by Trump's enmity toward Muslims, pointing to his comments on Twitter and on the campaign trail.
>> Donald J Trump is calling for a total and complete shutdown of Muslims entering the United States.>> The Justice Department says Trump's statements as a candidate carry no weight because he was not yet president. The adminstration argues the ban is needed to protect the US from terrorism by Islamic militants.
>> And the governemnet says this ban is needed for national security reasons. And that the President has the authority on the immigration law to decide who comes in and out of the country. And therefore this is a valid exercise of presidential power. The conservative majority court has already signaled it may side with Trump.
In December, it allowed the ban to go into full effect while the legal challenges played out.
