The U.S. government is detaining a record 12,800 migrant children, and the federal shelter system is close to capacity, The New York Times reports.

The number of detained migrant children is up from 2,400 kids in custody in May 2017. While the Trump administration did separate thousands of children from their parents at the southern border in an attempt to discourage others from entering the country, most of the minors now in custody crossed the border without a parent. There are 100 shelters across the United States, and they are operating at 90 percent capacity, up from 30 percent last year, the Times reports. The Trump administration announced on Tuesday it will triple the size of a temporary tent city in Tornillo, Texas, in order to house up to 3,800 children. Rep. Rosa DeLauro (D-Conn.) said this kind of facility is three times more expensive to operate than a fixed shelter, costing $750 per child, per day.

Data collected by the Department of Health and Human Services was shared with members of Congress, who passed it along to the Times, and those figures show that fewer kids are being released to live with relatives, family friends, and other sponsors. That's likely because sponsors now have to be fingerprinted, and most are undocumented and would risk being deported. Catherine Garcia

CNN legal analyst Jeffrey Toobin on Sunday agreed with the White House that the newly-released summary of Special Counsel Robert Mueller's report is a victory for President Trump — at least when it comes to allegations of collusion with Russia.

Toobin offered his analysis on CNN after Attorney General William Barr said that Mueller didn't find that Trump or his associates conspired with Russia to influence the 2016 presidential election. Toobin said that the report is a "total vindication of the president and his staff on the issue of collusion."

When it comes to whether Trump obstructed justice, though, this is "somewhat more complicated," Toobin observed. This is because the summary notes that while the investigation "does not conclude Trump committed a crime, it also does not exonerate him." It was Barr and Deputy Attorney General Rod Rosenstein that reached the conclusion that there was not sufficient evidence on obstruction, Toobin explains.

"That is still a vindication, but it's quite a different one than Mueller's total vindication of the president on the issue of collusion with Russia," Toobin said. He later added that although it may turn out that Barr and Rosenstein's conclusion on obstruction was the correct one, the fact that this came from "the president’s appointees" makes it a "very different thing from an independent conclusion."

Special Counsel Robert Mueller did not definitively conclude that President Trump or his associates during his 2016 presidential campaign colluded with Russian election interference, Attorney General William Barr's letter to Congress briefing them on the matter revealed on Sunday.

That revelation has already led to the White House declaring Mueller's findings a "total and complete exoneration" of Trump.

However, the report also did not make a conclusive decision on whether or not Trump obstructed justice during the investigation. Instead, it will be up to Barr "to determine whether the conduct described in the report constitutes a crime."

So, on the obstruction front, Trump still does not appear to be completely in the clear. Tim O'Donnell

President Trump declared victory on Sunday over the findings of Special Counsel Robert Muller's investigation into 2016 election interference, which he called an "illegal takedown."

Trump spoke with reporters after Attorney General William Barr told Congress that Mueller did not find that Trump or his associates conspired with Russia to influence the election. Mueller did not reach a conclusion about whether the president obstructed justice, saying the investigation did not exonerate Trump of this crime. Barr said that he and Deputy Attorney General Rod Rosenstein concluded there was insufficient evidence.

Trump called the investigation a "complete and total exoneration," saying that "it's a shame that our country had to go through this" and that "it's a shame that your president had to go through this." He also called the investigation an "illegal takedown that failed" and said that now "hopefully somebody is going to be looking at the other side." Watch Trump's comments on the Mueller report below.

House Judiciary Chair Jerrold Nadler (D-N.Y.) isn't completely convinced of President Trump's self-described exoneration.

Special Counsel Robert Mueller delivered his investigation of the Trump campaign's conduct surrounding Russian election interference to Attorney General Barr on Friday. On Sunday, Barr shared preliminary conclusions from the report with congressional Judiciary Committees, notably saying that Mueller's report "did not find that the Trump campaign or anyone associated with it conspired or coordinated with Russia in its efforts to influence the 2016 U.S. presidential election."

Still, Barr conceded that Trump "may have acted to obstruct justice," as Nadler put it in a series of tweets after receiving the letter. And while Barr said there wasn't enough evidence to charge Trump on that crime, Nadler's tweets implied that he'd like Barr to take a bit more time before drawing that conclusion, since Barr said he's still reviewing Mueller's report. Nadler also pledged to call Barr to testify before his committee "in the near future."

There has been a lot of uncertainty as to just how much of Special Counsel Robert Mueller's investigation into the Trump campaign's conduct amid Russian election interference would be made available to Congress and the public. That still remains unclear after Attorney General William Barr sent a letter to Congress briefing them on the "principle conclusions" of Mueller's investigation.

However, Barr did say that he intends to release as much of the report as possible, CNN reports.

He also said that Mueller will be involved in redaction efforts, particularly in terms of removing secret jury testimony, as well as material that is pertinent to ongoing investigations that have branched off from Mueller's initial investigation.

Barr wrote that once that process is complete he will "move forward expeditiously in determining" what can officially be revealed. Tim O'Donnell

The White House on Sunday called Special Counsel Robert Mueller's report on Russian election interference a "total and complete exoneration" of President Trump.

Press Secretary Sarah Huckabee Sanders reached this conclusion in a statement, saying that Mueller "did not find any collusion and did not find any obstruction."

Mueller's report did not find that Trump's campaign conspired with Russia to influence the 2016 election, according to Attorney General William Barr, although it did not make a determination on whether he obstructed justice. Barr quotes Mueller as saying that "while this report does not conclude that the president committed a crime, it also does not exonerate him." Barr says that he and Deputy Attorney General Rod Rosenstein concluded that there is not sufficient evidence to show Trump obstructed justice.

Trump's lawyer, Rudy Giuliani, similarly told CNN on Sunday that the report is a "complete exoneration" of Trump. Brendan Morrow
