'Start Here': Mueller report remix drops, Denver schools reopen, dead pigs slightly less dead

Here's what you need to know to start your day.

It's Thursday, April 18, 2019. Let's start here.

1. Muellermania

Today's the day: Americans finally get a chance to see what special counsel Robert Mueller devoted almost two years of his life to investigating.

Attorney General William Barr has scheduled a press conference for 9:30 a.m. Eastern time, but the 400-page report, built over 22 months, won't be delivered to Congress with Barr's color-coded redactions appended until at least an hour later.

Democrats don't love this plan.

"The attorney general appears to be waging a media campaign on behalf of President Trump, the very subject of the investigation at the heart of the Mueller report," House Judiciary Committee Chairman Jerry Nadler, D-N.Y., said Wednesday night.

Because reporters won't have access to the report before the press conference, ABC News Chief Legal Analyst Dan Abrams expects Barr to field questions primarily about the process of unveiling it rather than what's in it.

"Is this an example of transparency," Abrams asks on today's podcast, "or is this an example of Barr basically writing his third letter, in effect, about what’s in the Mueller report, as opposed to just letting the report speak for itself?"

2. #floridawoman

Students in Colorado are returning to class after the Miami high school student who flew to Denver on Monday and immediately bought a shotgun and bullets and threatened nearby schools appears to have shot herself.

The body of Sol Pais, 18, was found near a trail in Clear Creek, Colorado, ending a 36-hour FBI manhunt. Pais, authorities said, was obsessed with the 1999 Columbine shooting, the 20th anniversary of which is on Saturday.

"We have found that multiple past attackers have zeroed in on several specific attacks, Columbine being one in particular, as it related to school shooters," says John Cohen, an ABC News contributor and former acting undersecretary for the Department of Homeland Security. "There’s something about the Columbine attack that resonates with individuals whose grievances focus towards their school."

3. 'Overwhelming'

The influx of families approaching the U.S.-Mexico border is "overwhelming our ability to provide humanitarian aid," Kevin McAleenan, acting Secretary of Homeland Security, said on Wednesday, citing a new report.

The surge of families crossing the border, according to the report, has increased 600 percent in the last year, leading immigration officials to call it a "humanitarian crisis," ABC News' Lauren Pearle tells "Start Here."

"These families are hoping for asylum," Pearle says, "but, keep in mind, only about 15 percent of these families will actually get asylum, and that process can take over two years."

4. What is dead may never die

A team of Yale scientists has restored some cell function to the brains of 32 slaughtered pigs, according to a new study, blurring the line of what it means to be dead.

But experiments on these, uh, franken-swine, may raise ethical concerns.

"We have a huge problem in our society getting people to understand," Professor Art Caplan, a medical ethicist with the New York University School of Medicine, says on the podcast, "that once the brain totally and completely stops working, it can't come back."

Her all-female spacewalk may have been canceled, but NASA is trying to make it up to her by letting her stay in space through February 2020.

"I still have the grin on my face that won't seem to go away, just that I'm here every day," she told ABC News' David Kerley. "I don't necessarily count numbers or days, I just think about doing my best every day."

Koch, speaking to Kerley from the International Space Station, launched for the ISS on March 14.

"My primary message is to challenge yourself to reach farther than you think you can go," Koch added. "I think when we achieve a dream that's just outside of what we thought was in our reach, it has magnifying effects both for ourselves and what we can then strive to do in the future."
