Trump delivers remarks at the Hermitage on the occasion of the 250th anniversary of Jackson's birth, in Nashville, Tennessee Thomson Reuters White House officials traveling with President Trump on Wednesday "tried to cheer the president up" by showing him positive comments on the constitutionality of the Trump's travel ban made by Harvard law professor Alan Dershowitz on MSNBC that night, Politico reported.

Trump appeared at a rally at the Municipal Auditorium in Nashville, Tennessee around 7 p.m.

Shortly before going on stage, US District Judge Derrick Watson issued a temporary restraining order on Trump's revised executive order restricting travel from six majority-Muslim countries.

Dershowitz told MSNBC's Greta Van Susteren on "For The Record" on Wednesday that he wasn't surprised by the ruling in Hawaii, which was based on statements made by Trump during the campaign and by Rudy Giuliani shortly after the signing of the original executive order in January. However, he suggested that it was likely that not all federal judges would agree with that reasoning.

"I suspect we will quickly see some courts upholding this new regulation. We`ll have a conflict among the judges, and ultimately it will go to the Supreme Court," said Dershowitz, a leading proponent of civil liberties and a defense attorney who advised on the O.J. Simpson murder trial and worked on Nelson Mandela's defense team.

Dershowitz added that he didn't think Watson's reasoning in the district court ruling would be upheld at the Supreme Court.

At the Nashville rally, Trump cited Dershowitz's statement on MSNBC when talking about the ruling, which he called "terrible."

"Even liberal Democratic lawyer Alan Dershowitz, good lawyer, just said that we would win this case before the Supreme Court of the United States," Trump said.

Trump further blasted the ruling, saying that "the ruling makes us look weak" and suggesting that the judge ruled against the ban for "political reasons."

Shortly after the speech, Derkowitz went on CNN's Anderson Cooper 360 to comment again on the revised travel ban. He reiterated that he thinks Trump's ban will uphold in the Supreme Court, but still does not support Trump's order.

"I hope the president doesn't misinterpret my statements to say I support the order," he said to Cooper.

Since Trump's speech, a federal Maryland judge also placed a temporary block on Trump's travel ban.
