The Trump administration is seeking to override a rule that prevents immigrant children from being detained for more than 20 days, NBC News reported Thursday.

The Department of Homeland Security said it had created a new rule that will allow immigrant children to be detained with their parents indefinitely, and that the rule will go into effect in 60 days. The new rule will circumvent the 1997 Flores settlement, which determined that immigrant children seeking asylum in the U.S. could not be held for more than 20 days at a time, often leading to children being released with their parents at that time.

Officials tried to avoid those releases earlier this year by separating migrant children from their parents upon arrival in the U.S., but the administration ended that practice after significant backlash, though several hundred children remain separated. Now, a DHS official told NBC News that the new rule is a legal workaround because children will be held in Immigration and Customs Enforcement facilities that are evaluated by third parties.

In an announcement, administration officials said the evaluations will ensure that the facilities "satisfy the basic purpose" of the Flores settlement and keep children safe, while still closing "legal loopholes" that "significantly hinder" the government's ability to "promptly remove family units that have no legal basis to remain in the country."

Maverick is more than just Charlie's best friend — he's also his "seeing-eye" puppy.

Charlie and Maverick are golden retrievers, both owned by Adam and Chelsea Stipe of Mooresville, North Carolina. Charlie is almost 11 years old, and due to glaucoma, had his left eye removed in 2016 and his right in 2017. He still loves to play and go on walks but sometimes needs a little bit of help getting around. That's where Maverick comes in.

Maverick joined the Stipe family in January. Now four months old, Maverick walks next to Charlie, guiding him where he needs to go. Chelsea Stipe told NBC Philadelphia Maverick also noticed when Charlie would lose track of a toy, and would "pick it up and put it back in front of him to re-engage playtime." It took Charlie a bit of time to get used to Maverick, but now, they're inseparable. "They're both pretty crazy and special," Chelsea Stipe said. "They're definitely our entertainment."

At 94 years and 172 days old, Jimmy Carter is now the longest-living U.S. president.

Carter, the 39th president, was born on Oct. 1, 1924. When George H.W. Bush died in November, he was 94 years and 171 days old. Carter was also the first American president born in a hospital.

In office for one term, he has spent the last several decades dedicated to service, building houses with Habitat for Humanity and launching the nonpartisan and nonprofit Carter Center, which focuses on public policy. In 2002, he received the Nobel Prize. Carter announced in 2015 that he had cancer, which started in his liver and spread; he underwent surgery, and is now cancer-free.

Deanna Congileo, a representative of the Carter Center, told NBC News the organization is "grateful" for Carter's "long life of service that has benefited millions of the world's poorest people." Catherine Garcia

National Oceanic and Atmospheric Administration (NOAA) scientists on Thursday said "conditions are primed" for flooding in the Plains and Midwest that "could be worse than anything we have seen in recent years."

Mary Erikson, deputy director of NOAA's National Weather Service, said the "stage is set for record flooding now through May," because river levels are already high, soil moisture is above-normal, and there is substantial snowpack in the northern Plains, The Washington Post reports.

This week, there was deadly flooding in Nebraska and Missouri, and that could be just "a preview" of what might happen this spring. "This is potentially an unprecedented flood season," said Edward Clark, director of NOAA's National Weather Center. "It may become more dire in the coming weeks." The NOAA's spring flood outlook has 200 million Americans at risk, primarily those living near the upper, middle, and lower Mississippi River basins; the Great Lakes; as well as the eastern Missouri, lower Ohio, lower Cumberland, and Tennessee River basins.

In one year, Tanitoluwa Adewumi went from not knowing anything about chess to becoming New York's newest champion.

Adewumi, 8, started learning the game last year at his school, P.S. 116 in New York City. Adewumi and his family came to the U.S. from Nigeria two years ago, seeking religious asylum; they are Christians who fled to escape the terror group Boko Haram. Adewumi's coach, Shawn Martinez, said the third-grader loves to play and is always practicing. "He smiled every time he did anything on the board or learned something new," he told NBC New York. "I could just tell this game was for him."

Over the weekend, Adewumi kept his undefeated streak alive, winning his age group in the New York State Primary Chess Tournament. Adewumi will soon have a place to display his huge trophy: The family has been living in a homeless shelter, but a GoFundMe started for them this week has raised more than $160,000, and they will soon move into their own home.

Adewumi is gearing up for the national championship in May, and is inching closer to his goal. "I want to be the youngest grandmaster in the world," he said. Catherine Garcia

While he believes President Trump is "morally unfit" to be the country's leader, former FBI Director James Comey isn't hoping Special Counsel Robert Mueller's final report will reveal Trump is "a criminal."

In an op-ed published Thursday night in The New York Times, Comey declares he's just happy Trump hasn't shut down Mueller's investigation, arguing that if it the probe continues unimpeded, "justice will have prevailed and core American values will have been protected at a time when so much of our national leadership has abandoned its commitment to truth and the rule of law."

Comey, who was fired by Trump in 2017, said he doesn't care at all whether Mueller concludes Trump "knowingly conspired with the Russians in connection with the 2016 election or that he obstructed justice with the required corrupt intent." He does have one hope, though: that Trump is not impeached and removed from office before his term is over.

"I don't mean that Congress shouldn't move ahead with the process of impeachment governed by our Constitution, if Congress thinks the provable facts are there," Comey wrote. Rather, his concern is that if Trump is removed from office, "a significant portion of this country would see this as a coup, and it would drive those people farther from the common center of American life, more deeply fracturing our country."

Marine Corps Gen. Robert Neller wrote in two internal memos that President Trump's "unplanned/unbudgeted" deployment of troops to the southern border has posed "unacceptable risk to Marine Corps combat readiness and solvency," the Los Angeles Times reports.

The memos obtained by the Times are dated Feb. 19 and March 18 and addressed to Acting Defense Secretary Patrick Shanahan and Navy Secretary Richard Spencer.

Neller wrote that because funds have been shifted to border security and recovery costs from Hurricanes Michael and Florence are high, he has had to postpone much-needed base repairs, and cancel or scale back military training in Indonesia, Scotland, Mongolia, Australia, and South Korea. Marines "rely on the hard, realistic training" of the exercises, he said, to "develop the individual and collective skills necessary to prepare for high-end combat."

These memos, Sen. Richard Durbin (D-Ill.) said, show the Pentagon should not be diverting funding at Trump's whim. "If the president won't listen to the American people or Congress, then listen to the commandant of the Marine Corps," he said in a statement. Catherine Garcia
