ACLU says it plans to use Trump's tweets on travel ban in its Supreme Court argument

The ACLU said on Twitter Monday that it would use President Donald Trump's latest series of tweets about the travel ban in ongoing court battles against the ban.

After the London terrorist attack that killed seven people on Saturday, Trump took to Twitter to renew calls for his executive order to ban travel from six majority-Muslim countries.

"People, the lawyers and the courts can call it whatever they want, but I am calling it what we need and what it is, a TRAVEL BAN!" Trump tweeted on Monday morning.

He had tweeted that the US needs "the travel ban as an extra level safety" a few days before.

Federal courts have blocked Trump's travel restrictions at every turn since his administration rolled them out in late January, just days after Trump took office.

Late last month, the Fourth Circuit Court of Appeals in Richmond, Virginia, refused to reinstate the revised immigration order. Chief Judge Roger L. Gregory argued for the majority that discriminatory statements Trump made about Muslims on the campaign trail revealed "his intent, if elected, to ban Muslims from the United States."

Attorney General Jeff Sessions said last week that the Justice Department will ask the Supreme Court to review the case.

The American Center for Civil Liberties, which frequently speaks out against Trump's travel ban in courts, said on Twitter that it may use Trump's tweets about the ban in its argument at the Supreme Court.

Earlier this week, the ACLU responded to Trump's tweets, saying the organization is "glad we both agree the ban is a ban." In the past, White House Press Secretary Sean Spicer said that the order called for a vetting system rather than a ban.
