Airline passengers weren't the only ones who were impacted by President Trump's executive order restricting travel and immigration from seven Muslim majority nations.

Attorneys say several cruise ship passengers at Port Canaveral were detained by Customs agents as they got off the ship Sunday.

When attorney Ruth Singer of Suntree, and some fellow attorneys found out Sunday what had happened on the Majesty of the Seas, they hopped in a car and headed there right away.

The email was a blast from the ACLU chapter based in Miami, saying six to seven people of Syrian descent had been detained at Port Canaveral.

Singer was just half an hour away from the port and says she had to help in a situation she calls an "injustice."

"Particularly for those who are lawful residents who already have legal papers, that have given them the legal ability to come in here, and essentially revoke it without any notice or due process," Singer said. "I think this is a broad ban, that targets a specific religion or specific race. And I think it's inappropriate for those reasons."

Singer says she and the fellow attorneys were denied access to the detainees.

One of them was a mother with a 20-year Green Card who was cruising with three children. All of the children were born in the United States.

Some of the detainees, according to Singer, were held for more than six hours, then released. It meant missing flights back home after the cruise.

On Sunday night some 100 people held a vigil outside the port's Exploration Tower. They lit candles and some prayed for a resolution.

An ACLU spokesperson from South Florida said the group is getting several calls from concerned family and friends of loved ones who will soon be trying to enter the country.
