what does that have to do with the travel ban?Are you one of those hypocrites who always demands others be specific and then just spouts platitudes and right wing tropes recited by your orange master, never grappling with specific facts yourself?
I don't have the filing or the TRO application or declarations in support, but I can guess one ground would be the executive order overruling the act of Congress, a coequal branch with province over lawmaking, and which afforded immigrant political refugees legal rights to asylum in the USA.
The refugee's are more in legal question -there are a couple of laws that need to be looked at.
But that would not involve state AG's ( no standing)
