So far, 10 suspicious packages -- each with possible explosive devices inside -- have been located by authorities. Here's what we know about the eight targets:
- George Soros: The package found Monday and appeared to be an explosive device. There was a controlled detonation; the device is secured and remains in New York.
- Hillary Clinton: The package was addressed to Clinton residence in Chappaqua, New York, and intercepted Tuesday night by the Secret Service during routine mail inspection
- Barack Obama: The package was intercepted in Washington, D.C., during routine mail screening procedures, the Secret Service said.
- John Brennan (sent to CNN offices): The "live explosive device" was delivered by courier to CNN's offices in New York. The NYPD said an envelope containing white powder also was found as part of the device's original packaging.
- Eric Holder (found at Rep. Debbie Wasserman Schultz's office): The package was addressed to the former attorney general, but sent to the Florida office of Schultz, whose return address was on the package.
- Rep. Maxine Waters: One package was sent to the Democratic congresswoman's office in DC and a second package addressed to her was found at a postal facility in Los Angeles. It matches the description of those sent to the other officials.
- Joe Biden: The FBI says two packages were found in Delaware addressed to former Vice President Joseph Biden.
- Robert De Niro: The package has markings similar to the pipe bomb packages recently mailed nationwide to top Democrats, sources said.
This map shows the locations of the packages. (Note that the second package for Waters was found in California.)
Take a look:
Speaking with reporters on Thursday morning, White House press secretary Sarah Sanders defended President Trump's criticism of the media in the wake of the explosive packages that were mailed to CNN and some of his critics.
"The President has condemned violence in all forms, has done that since Day 1, will continue to do that. But certainly feels that everyone has a role to play," Sanders said.
When asked by CNN's Abby Phillip about whether he regrets calling political opponents "evil," Sanders said that Trump feels "we should call out despicable acts, which is exactly what he has done over the last 24 hours."
When pressed about whether the term "evil" was appropriate, Sanders lashed out at CNN: "It's a word people have used on your network a number of times, not only to describe the President but many people that work in this administration."
"You guys continue to focus only on the negative. There is a role to play," she continued. "Yesterday, the very first thing that the President did was come out and condemn the violence. The very first thing your network did was come out and accuse the President of being responsible for it. That is not okay. The first thing should have been to condemn the violence."
But that's not true: "That's not the first thing we did as this happened. We reported the news, in fact," CNN's Jim Sciutto just said on air -- Sciutto and Poppy Harlow covered the story live on air after CNN evacuated its newsroom when a bomb was found in the mailroom downstairs.
Addressing a packed audience at the Justice Department for an event on combating the opioid crisis, Attorney General Jeff Sessions addressed the suspicious packages found over the last several days.
He said that it points to the “courage our law enforcement officers display,” and wanted to “thank all law enforcement.”
Sessions said that he briefed President Trump yesterday, along with FBI Director Chris Wray and Deputy Director Bowdich, but did not provide any further details.
Stan Rosenfield, spokesperson for Robert De Niro, tells CNN he has called de Niro but has not yet reached him yet this morning.
When asked for his reaction, Rosenfield said:
Multiple law enforcement officials tell CNN they have located the package in Delaware that was addressed to former Vice President Joe Biden.
FOX 29's Chris O'Connell obtained a photo of the suspicious package intended for Biden. It was intercepted at a Wilmington, Delaware, post office.
The photo appears to have the same packing, postage stamps and return address — with all its misspellings — as the others.
Flying in a helicopter above a US Postal facility in New Castle, Delaware, CNN affiliate WPVI spotted a bomb containment unit.

Despite today's news, mail bombs are incredibly rare.
The US Postal Inspection Service processes more than 170 billion pieces of mail every year, and only a tiny fraction of those -- just 16 over the last few years -- were investigated as mail bombs.
That works out to an average of less than 1 in 10 billion.
Here are some of the tell-tale signs of a suspicious package.
If you come across a suspicious package, here are some tips for what to do next, according to the Department of Homeland Security.
- Leave the package alone, clear the area and contact emergency personnel.
- Wash your hands and other exposed skin with soap and water.
- Cordon off the immediate area, and shut down all equipment there.
- If possible, and without disturbing the mail, jot down what you can about the package (what it looks like, markings, the name and address on it).
If you observe any suspicious activity that requires an immediate response, please call 911 or contact your local law enforcement.
Former CIA Director John Brennan, whose name was on the bomb sent to CNN's New York office, just responded to President Trump's tweet this morning bashing the "Mainstream Media."
Brennen is a frequent Trump critic who saw his security clearance revoked by President Trump this summer.
Here's Brennan's Twitter response to the President:
CNN affiliate WPVI reporter Jeannette Reyes observed an increased police presence at a Delaware US Postal facility.
We don't know what this is about, but we do know authorities believe they’ve found the package sent to former Vice President Joe Biden, a Delaware resident.
