Steeve Briois, the National Front party's vice president and a member of Le Pen's campaign, told Agence France-Presse that they would certainly be open to copying Trump's ban in France.
“And why not?” said Briois, who also is the mayor of Henin-Beaumont, a city about 125 miles north of Paris. “We are no longer in the world of the Care Bears. We are in a horrible world, so sometimes you have to take measures of authority, even if it shocks.”
Trump also said he would give priority to Christian refugees over those of other religions, according to the Christian Broadcasting Network. The president and his supporters have continued to insist it is not a ban on Muslims.
Throughout the weekend, the order sowed confusion at numerous airports as travelers from the affected countries were denied entry. The ban also drew lawsuits, massive protests and sharp rebukes from domestic lawmakers and leaders around the world.
Despite the chaos, Briois on Monday said it was Trump's prerogative to enact such a ban.
“It is true that the United States are a target for jihadists so if [Trump] wishes to protect himself by barring entry on his territory for people from those countries, that is his right,” Briois told AFP. “It is unfortunate for those [caught up in the ban] who have nothing to do with it.”
Le Pen has not spoken publicly about the travel ban, according to the Local. Since the beginning of her campaign, she has maintained that she wants to pull France out of the European Union, reinforce the country's borders and crack down on immigration.
This month, during Trump's transition period, Le Pen was spotted at Trump Tower in New York, although she did not say whether she met with the then-president-elect while there.
Over the weekend, however, Le Pen posted a defense of Trump on Twitter.
“What bothers the media and politicians is that Trump respects his commitments and implements his programs,” Le Pen tweeted Saturday.
A recent poll shows Le Pen with a slight lead in the election's first round in April, with 25 percent of the votes, Reuters reported.
Meanwhile, center-right candidate Francois Fillon, who won the national primaries in November, came in at 21 to 22 percent of the vote in that poll, ceding some votes as he is caught up in an employment scandal involving his wife. Fillon has said he may drop out of the presidential race if a judge decides to pursue a formal case against him.
Seen as Le Pen's toughest competitor, Fillon has also taken a hard-line stance on immigration. He reiterated that stance in a tweet Sunday, saying he wanted “strict administrative control over the Muslim faith” in France.
The poll showed that centrist candidate Emmanuel Macron would earn 20 to 21 percent of the vote.
On Sunday, Socialist Benoit Hamon won the country's leftist primary. Experts say the leftist party is very unlikely to win the presidential race, given the rise of populism and nationalism around the world.
France's unpopular president, François Hollande of the Socialist party, announced last month that he would not seek reelection despite being eligible for another term.
The two rounds of the election will take place in late April and early May.
