US President Donald Trump is considering issuing a new travel ban executive order, but the administration could still escalate a legal dispute over the original travel ban order to the US Supreme Court.
In a step that triggered the most serious legal confrontation yet for the new Republican administration, Mr Trump two weeks ago issued an executive order banning entry into the US by refugees and citizens of seven Muslim-majority countries, triggering nationwide protests and legal challenges.
A federal judge in Seattle last week issued a temporary restraining order putting the travel ban on hold.
That suspension was upheld by an appeals court in San Francisco on Thursday, raising questions about Mr Trump's next step.
Speaking to reporters aboard Air Force One on the way to Florida from Washington on Friday (local time), Mr Trump said he was considering "a brand new order" that could be issued as soon as Monday or Tuesday if he decides to move in that direction.
After a White House official said the administration was not planning to escalate the legal dispute to the Supreme Court, chief of staff Reince Priebus told reporters such a move was still possible.
"Every single court option is on the table, including an appeal of the Ninth Circuit decision on the TRO (temporary restraining order) to the Supreme Court, including fighting out this case on the merits," Priebus said.
"And, in addition to that, we're pursuing executive orders right now that we expect to be enacted soon that will further protect Americans from terrorism."
Earlier in Washington, Mr Trump promised to take action "very rapidly" to protect US citizens in light of "tremendous threats" against the country.
"We'll be doing things to continue to make our country safe," Mr Trump said during a news conference with Japanese Prime Minister Shinzo Abe.
"It will happen rapidly. We will not allow people into our country who are looking to do harm to our people."
Mr Trump's order, which he called a national security measure meant to head off attacks by Islamist militants, barred people from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen from entering for 90 days and all refugees for 120 days, except refugees from Syria, who are banned indefinitely.
Mr Trump could rewrite the order to explicitly exclude green card holders, or permanent residents, said a congressional aide familiar with the matter.
Doing that could alleviate some concerns with the original order expressed by judges in the Ninth Circuit court where it is being tested.
On Air Force One, Mr Trump said regarding the Ninth Circuit court fight: "We will win that battle. The unfortunate part is that it takes time statutorily ... We need speed for reasons of security."
