President Joe Biden discussed efforts to address the unprecedented flow of migration along the U.S. southern border in a Friday afternoon call with Mexican President Andrés Manuel López Obrador.

Biden and the Mexican leader spoke for 52 minutes, the White House said. Press secretary Jen Psaki called the conversation was "very constructive" and said it focused on coordination around migration and economic issues.

The planned end on May 23 of the public health ban on asylum seekers could lead to a rush of migrants to the U.S.-Mexico border. Lopez Obrador tweeted that the conversation was "cordial" and focused on "issues of interest to the bilateral relationship."

López Obrador said, “It’s important that there’s this communication, to listen to President Biden who has treated us with respect, as President Trump also treated us with respect, and we have to ensure a good relationship."

López Obrador is scheduled to visit Central American countries along with Cuba next week. He plans to speak to counterparts about economic development and social programs.

WASHINGTON — White House press secretary Jen Psaki on Friday reiterated that the Biden administration remains resistant for now on banning Russian oil imports, raising concerns that such a ban could have a negative impact for U.S. and European economies. She added, however, that the administration was “looking at options we could take right now to cut U.S. consumption of Russian energy,”

Psaki also called on Russian forces to withdraw from the Zaporizhzhia nuclear plant in southeastern Ukraine. Russian troops seized the plant earlier Friday.

“The best step for nuclear safety would be for Russia to immediately withdraw,” Psaki said.

Officials from the U.N. and Ukraine said no radiation was released from the Russian attack at Europe's largest nuclear power plant in Ukraine, and firefighters have extinguished a blaze at the facility.

The fire at the Zaporizhzhia Nuclear Power Plant in Enerhodar was extinguished early on Friday morning, hours after Russian forces began shelling the facility.

The International Atomic Energy Agency's director-general said Friday the building hit by a Russian "projectile" at the plant was "not part of the reactor" but instead a training center at the plant.

Nuclear officials from Sweden to China also said no radiation spikes had been reported.

The fire at the plant sparked fears of the 1986 nuclear disaster at the Soviet-run Chernobyl plant in Ukraine. Even though the nuclear plant is of a different design than Chernobyl and is protected from fire, nuclear safety experts and the International Atomic Energy Agency warn that waging war in and around such facilities presents extreme risks.

Though President Joe Biden campaigned on the promise of making America a more welcoming place for immigrants, press secretary Jen Psaki issued a warning to Central Americans who are considering coming north to the United States.

"This is not the time to come to the United States," Psaki said during a briefing on Tuesday. "We need the time to put in place an immigration process where people can be treated humanely."

Psaki said the Biden administration is "trying to repair the damage and the horrific actions of the prior administration" when it comes to immigration, particularly when it comes to reuniting children separated from their families.

However, she added that it would take time for the administration to implement changes to immigration policy.

"We want to put into place an immigration process here that is humane, that is moral, that considers applications for refugees, that considers applications for people to come into this country at the border in a way that treats people as human beings. That's going to take some time," Psaki said. "It's not going to happen overnight."

Some of that work will resume later on Tuesday, as Biden plans to sign three executive orders on immigration.

The first will set up a task force — headed by Biden's nominee for Homeland Security Director, Alejandro Mayorkas — that aims to reunite immigrant children who were separated from their parents at the border under a Trump-era policy.

The second executive order will call for an investigation into causes of migration and will call for an end to a Trump-era policy that forced asylum seekers who entered through the U.S.'s southern border to remain in Mexico.

The third and final order will establish a task force on "New Americans" that will aim to promote immigrant integration and inclusion in the immigration systems.

The executive order signings will take place later in the day on Tuesday, following the pending confirmation of Biden's nominee for Director of Homeland Security, Alejandro Mayoras.

The White House briefing comes a day after Biden met with Republican lawmakers, who proposed a counteroffer to Biden's $1.9 trillion COVID-19 stimulus package. The slimmed-down Republican package totaled about $600 billion.

Psaki called Biden's meeting with Republicans "civil" and "constructive" but said a large gap remains in COVID-19 negotiations. She added that Biden does not plan to lower the price tag of his proposed bill.

Psaki's briefing took place just moments after Biden concluded a call with the Democratic Senate caucus regarding COVID-19 stimulus funding.
