In the city's downtown battery park, hundreds of protesters also braved the winter chill to demonstrate against the president's executive order.

The Lafayette Square before the White House was packed by protesters against Trump's ban from noontime as more demonstrators were still arriving, witnesses said.

They wielded poster boards bearing messages such as "Ban Trump" "Refugees Welcome" and chanted "No hate! No fear! Refugees are welcome here!"

Protests are also scheduled throughout the day in Philadelphia, Atlanta, Los Angeles, Seattle and Chicago, said a cnn report.

In Boston's Copley Square, thousands of people also gathered to protest the immigration ban, according to a report from the USA Today.

Earlier on Sunday, White House counselor Kellyanne Conway said the international travel disruptions in the wake of the ban was "a small price to pay" for greater security of the United States.

On contrary, Senate Minority Leader Chuck Schumer on Sunday said Democrats are considering legal actions to overturn the order.

A federal judge in New York on Saturday night granted an emergency stay temporarily halting the removal of people who, though with previously approved refugee applications or with valid visas, had ben detained following Trump's refugee and immigration order.

Similar rulings were later issued in Virginia, Massachusetts and Washington state, said a TheHill news daily report.
