"That's a legal standard that was invented this morning". Dershowitz argued for the second, more moderate ban put forth by the White House after courts struck down the original order and said it's incorrect to assert the president's lack of authority when it comes to barring entry.
The Department of Justice has retorted to the Fourth Circuit that there is no language in the executive order referring to religion and that courts should not have considered Trump's campaign statements about Muslim countries.
"We really weren't sure if they were going to take it; it's a messy case, and it's a big deal" for the Supreme Court to go up against a presidential administration, said Eliza Collins, a congressional reporter for USA Today.
Likewise, the justices said, refugees can travel to the USA if they demonstrate those connections - contrary to the part of Trump's executive order suspending the nation's refugee program.
The court ruled yesterday that Trump's temporary moratorium could go forward in some cases while justices prepare to hear full arguments in October.
Trump's revised executive order, issued in March, limited travel from six mostly Muslim countries for 90 days and suspended the nation's refugee program for 120 days. It blocks a ban for people who can demonstrate a USA connection.
Q What about refugees coming from places like Syria or other war-torn countries? He added that the order "allows the travel suspension for the six terror-prone countries and the refugee suspension to become largely effective".
Nicky Smith, executive director of the International Rescue Committee's Seattle office, said she worries about refugee children traveling to the US for medical care. "[And it's] an important move that all the other courts, prior to the Supreme Court, refused to acknowledge".

"As it is imperative that the traveling public maintain confidence in an industry so vital to our nation's economy, we ask that the Administration set clear implementation guidelines in the interim so uncertainty, and the travel disruptions likely to result, are kept to an absolute minimum", ASTA said.
Q When does this take effect? .
Implementing the ban may cause chaos at airports, experts warn.
Q Is this a final ruling? .
Until then, people entering the USA from one of the six countries "who lack any bona fide relationship with a person or entity" in the country will remain barred.
In Monday's ruling, the high court gave a few examples of connections that qualify. The plans were described by a senior official who was familiar with them, speaking on condition of anonymity because this person was not authorized to discuss them publicly by name.
But, the court said the injunctions were too broad to also include barring enforcement of the ban against foreigners who have no connection to US. Will the travel ban even still be an issue by the time the justices hear arguments?
Mr Stephen Legomsky, chief counsel for US Citizenship and Immigration Services under former president Barack Obama, said lawsuits could claim that a bona fide relationship was ignored. He also said he's confident organizations challenging the president's ban, like his, will eventually be victorious.
There may be less confusion as the ban is partially reinstated.
