"An unprecedented number of unaccompanied migrant children are at risk of spending the rest of their childhoods in federal custody," CBS News reported Tuesday evening, citing an interview with the head of the Health and Human Services Department's Office of Refugee Resettlement (ORR) and a tour of an ORR detention center outside Brownsville, Texas. At least one migrant child has been in U.S. custody going on four years, CBS News' Manuel Bojorquez reports.

More than 4,000 of the 10,100 "unaccompanied" children currently in ORR custody have been designated Category 4 cases, meaning they have no identified sponsor to host them in the U.S., ORR director Jonathan Hayes told CBS News in June. If they aren't released to a suitable sponsor by their 18th birthday, the migrant children are handed over to Immigration and Customs Enforcement custody, usually a precursor to deportation.

The number of Category 4 child migrants has risen sharply under President Trump, and the percentage of children released from ORR custody dropped dramatically in fiscal 2018, agency records show. Former ORR officials said Trump's hardline immigration policies and onerous sponsorship requirements have prevented relatives from stepping up to request custody of the detained children. Ricardo de Anda, a Texas lawyer who successfully sued ORR to allow a Category 4 migrant to go live with a sponsor family, said "the reason children are stacking up in these detention camps is because ORR does not allow qualified American families to take these children in."

Life for children housed at the 168 ORR facilities in 23 states is unstable and sometimes dehumanizing, lawyers and former ORR officials tell CBS News. Under the Flores Agreement, migrant children must be released to suitable sponsors as soon as possible, but due to the uptick in Category 4 designations, "they could be indefinitely in our custody, which is not a healthy situation for children," former ORR Director Bob Carey tells CBS News. "And these children are for the most part already traumatized." Peter Weber

Sen. Elizabeth Warren (D-Mass.) did not want to answer that one.

Warren on Saturday steered away from directly responding to a question about whether she would release her tax returns from before 2008 if her fellow Democratic presidential candidate South Bend, Indiana, Mayor Pete Buttigieg made his fundraisers open to the press.

The senator didn't say yes or no, but she made the argument she was focusing on the present. To her point, she has already released 10 years worth of her tax returns, which is more than President Trump or former President Barack Obama ever released. But Warren has also recently called for Buttigieg to release the names of his clients when he worked for the consulting firm McKinsey & Co. He began that job in 2007.

Buttigieg's camp responded to Warren already, and called for her to release the returns in a show of transparency. Tim O'Donnell

The FBI is keeping its investigation into the shooting that killed three people Friday at Naval Air Station Pensacola in Pensacola, Florida, tightly wrapped, but some information has made its way through.

The New York Times, for instance, reports that the suspected Saudi Arabian gunman — identified as Second Lt. Mohammad Saeed Alshamrani, an aviation student at the base who served in the Saudi air force — appears to have been self-radicalized. There is no evidence he had any ties to international terrorist groups, an initial assessment from American intelligence and counterterrorism officials revealed.

A motive reportedly remains unclear right now, though the SITE Intelligence Group which monitors jihadist activity, found a Twitter account that could not be independently verified, but had a name matching the suspect's. It contained posts criticizing U.S. foreign policy and quoting former al Qaeda leader, Osama bin Laden, per the Times.

The FBI is still investigating whether the suspected gunman acted alone, as well. The Associated Press reports he had a dinner party with three other students earlier this week. They reportedly watched videos of mass shootings while there, a U.S. official told AP, and one of those students reportedly videotaped the building where the shooting was taking place, while the other two watched from a car. The official said 10 other Saudi students were being held on the base, while several others were unaccounted for.

As of now, though, there hasn't been any indication about whether the shooting was part of a larger operation, but that hasn't prevented some lawmakers from reaching their own conclusions. Tim O'Donnell

The House Judiciary Committee released a report Saturday geared toward defining what the Constitution's framers considered an impeachable defense.

The report comes after four legal experts testified about the subject Wednesday in the committee's initial hearing in President Trump's impeachment inquiry. The report, which traces impeachment's origins to monarchical England, doesn't conclude that Trump should be impeached, although Judiciary Committee Chair Rep. Jerrold Nadler (D-N.Y.) didn't mince words when announcing its release.

Ultimately, though, the committee is leaving that decision up to the House as a whole. Still, there's seemingly some hints at what future articles of impeachment — which House Speaker Nancy Pelosi (D-Calif.) asked committee chairs to draft — might look like.

Trump appears to have heard about the report and was quick as always to argue over Twitter that he was putting the U.S., not himself, first in his dealings with Ukraine. Tim O'Donnell

Congress is on the verge of implementing paid parental leave for all federal workers.

A tentative bipartisan agreement was struck during Congress' negotiations over its annual defense bill. Draft language includes a provision that would allow 2.1 million civilians who work for the U.S. government to take paid leave for 12 weeks to care for a new baby after birth, adoption, or the initiation of foster care, multiple people familiar with the agreement told The Wall Street Journal.

Currently, military members can take 12 weeks of paid parental leave, but civilian federal employees only receive unpaid parental leave and instead have to use accrued annual or sick leave to get paid during that time, per the Journal.

The White House is backing the deal, and Ivanka Trump reportedly played a role in the negotiations.

That has Democratic lawmakers optimistic the provision will pass.

Many lawmakers view this as a first step toward guaranteeing paid parental leave for all Americans, including those who work in the private sector, which Congress hopes will eventually match the same standard. "This will be a crucial win for federal employees and their families and a significant development in our ongoing fight for comprehensive paid family and medical leave for all Americans," Rep. Carolyn B. Maloney (D-N.Y.) said. Read more at The Wall Street Journal. Tim O'Donnell

President Trump received some good news and some bad news from the Supreme Court on Friday.

First, Justice Ruth Bader Ginsburg temporarily blocked a congressional subpoena for President Trump's financial records from Deutsche Bank. The decision comes after Trump's emergency request to block a lower court ruling that required him to hand over the records as part of the House Financial Services and Intelligence Committees' investigation into Trump's relationship with the bank.

The stay on the ruling doesn't let Trump off the hook in the long run, however. It will remain in place until Dec. 13 while the Supreme Court deliberates on whether to grant a longer stay and give Trump's legal team time to prepare a formal appeal. But ultimately, it doesn't say much about how the Court will rule.

Meanwhile, in news that left the Trump administration — particularly the Justice Department — more disappointed, the Court rejected the White House's request to go ahead with a plan to carry out the first executions of federal death row inmates since 2003. The justices left a federal judge's hold on four executions scheduled by U.S. Attorney General William Barr in place, though the U.S. Court of Appeals for the District is now considering the case and should make a ruling within two months.

Financial compensation may soon be on the way for some of California's wildfire victims.

Pacific Gas & Electric agreed Friday to pay $13.5 billion in damages to victims of four wildfires that occurred in the state between 2015 and 2018. Among the fires covered in the claims is the 2018 Camp fire — California's deadliest blaze — which killed 85 people and destroyed 18,800 structures.

If accepted by a bankruptcy judge, the settlement will go to people who lost loved ones, property, or both, as well as government agencies and attorneys who pressed the claims. Some of the blame for the fires has been directed at faulty or aging PG&E equipment.

"There have been many calls for PG&E to change in recent years," said Bill Johnson, the CEO and president of PG&E. "PG&E's leadership team has heard those calls for change, and we realize we need to do even more to be a different company now and in the future. We will continue to make the needed changes to re-earn the trust and respect of our customers, our stakeholders, and the public."

The settlement comes after the company agreed to a $1 billion deal with cities, counties, and other public entities, as well as an $11 billion agreement with insurers and others covering claims for wildfires in 2017 and 2018. Victims seeking compensation will have until the end of the year to file claims. Read more at NBC News and NPR. Tim O'Donnell
