Just before a midnight deadline on Tuesday, the Trump administration informed Congress that Iran is living up to the terms of a 2015 nuclear deal brokered under former President Barack Obama, and was thus eligible for extended sanctions relief. During the 2016 campaign, President Trump was a vocal critic of the deal, negotiated between Iran, the U.S., and five other world powers, but he has given mixed signals on his intentions since taking office. The agreement rolls back Iran's nuclear programs in return for unfreezing billions in Iranian assets.

In a letter to House Speaker Paul Ryan, Secretary of State Rex Tillerson certified Iran's compliance, but said the Trump administration is undertaking an interagency review of the deal, led by the National Security Council, to see if it "is vital to the national security interests of the United States." Iran, he added, "remains a leading state sponsor of terror, through many platforms and methods." The Islamic republic is still subject to non-nuclear sanctions and remains on the State Department's list of state sponsors of terrorism. The White House must update Congress on Iran's compliance every 90 days. Peter Weber

White House Press Secretary Sarah Huckabee Sanders isn't backing down from her verbal attacks on CNN — less than a day after the network was literally sent a bomb in the mail.

In a Wednesday night tweet, Sanders criticized CNN President Jeff Zucker for choosing "to attack and divide" even though President Trump "asked Americans 'to come together'" amid a wave of "political violence." And when talking with reporters on Thursday morning, Sanders again piled some blame on CNN, CBS News' Mark Knoller reports.

CNN's New York newsroom evacuated Wednesday when it received one of the many packages containing explosive devices. Zucker responded to the attack by saying Trump and Sanders have a "complete lack of understanding ... about the seriousness of their attacks on the media." Sanders hit back at Zucker's criticism, claiming that the "first thing CNN did was to accuse [the president] of being responsible for bomb devices," per a tweet from Knoller.

As the caravan of Central American migrants continues to make its way toward the southern border of the U.S., the Trump administration is calling in for back-up.

Secretary of Defense James Mattis will soon deploy at least 800 troops to provide "fencing, wall materials, and other technical support" at the border where the migrants will be arriving, CNN reported Thursday. Administration officials told CNN that border patrol agents will still be the ones to actually prevent the migrants from crossing, but troops will provide aid, including tents and medical assistance for the officers there. Already 4,000 members of the National Guard have been authorized to join the efforts at the border, though only about 2,100 are there right now.

The 800 additional troops would reportedly be ready at the border next week, although the caravan of migrants will not be there at that point. The migrants are still about 1,000 miles south of the border, and CBS News reports that they likely won't reach the U.S. until December. These thousands of migrants are coming from a variety of Central American countries, primarily Honduras, with many fleeing poverty and violence at home. More than 1,500 migrants have dropped out of the caravan to seek asylum in Mexico, so it's unclear how many migrants will travel all the way to the U.S. President Trump previously suggested some in the caravan could be "unknown Middle Easterners," but admitted he had no evidence to support this statement.

Saudi Arabia has a new explanation for Jamal Khashoggi's death.

The country's attorney general announced Thursday that the murder of the U.S.-based Saudi journalist was "premeditated" the state-run Saudi Press Agency reported. That's a change from Saudi Arabia's earlier story, which declared that Khashoggi died during a "botched interrogation."

This new conclusion, which more closely matches what Turkish officials say happened, draws from a joint investigation involving Saudi Arabia and Turkey, per the press agency. Turkey has long pushed responsibility on the Saudi government, with President Recep Tayyip Erdogan saying Tuesday that the "savage" murder was pre-planned by Saudi officials. Saudi Crown Prince Mohammed bin Salman has maintained that he had no knowledge of the "rogue" operation.

Khashoggi, a journalist who criticized the Saudi government, was killed in Istanbul's Saudi consulate on Oct. 2. CIA Director Gina Haspel is currently in Riyadh investigating, and has reportedly heard what Turkey claims to be audio of Khashoggi's murder. The U.S. plans to revoke visas from Saudi suspects they've already identified, and is considering sanctions. Kathryn Krawczyk

Two days after her controversial blackface comments, NBC may have already ended Megyn Kelly's show.

Megyn Kelly Today on Thursday aired an episode recorded in August, and NBC News said that re-runs would air for the rest of the week "given the circumstances," CNN's Brian Stelter reported. That's apparently referring to the controversy sparked by comments Kelly made Tuesday during a segment about Halloween costumes; Kelly had said that wearing blackface as part of a costume is not racist and suggested that those who think it is are just being too sensitive.

The backlash was immediate, and even Kelly's colleagues weren't happy — the hosts of Today called her comments "ignorant" and "racist." Kelly apologized for the remarks in an internal email Tuesday, and she issued another apology on-air Wednesday, saying, "I was wrong, and I'm sorry." Later on Wednesday, reports began to emerge that Kelly's show might be coming to an end. The Hollywood Reporter first wrote that it would be gradually winding down over the course of the year, and that Kelly would shift to a different role at NBC focusing on breaking news. The TV personality was reportedly already interested in ending her show in the near future, unrelated to her controversial blackface comments.

Now, however, CNN reports that Kelly's show might not return at all and her exit is "imminent," meaning Wednesday's apologetic broadcast may turn out to be her final episode. Brendan Morrow

Another possible explosive device addressed to a critic of President Trump has reportedly turned up.

Law enforcement officials say a suspicious package sent to former Vice President Joe Biden has been intercepted in Delaware, NBC News reports. CNN previously reported that authorities were attempting to locate this package, which had been returned to sender because the address was incorrect.

This package to Biden is reportedly similar to the ones containing explosive devices that were previously sent to Democratic politicians. On Wednesday, former President Barack Obama, former Secretary of State Hillary Clinton, former Attorney General Eric Holder, former CIA Director John Brennan, and Rep. Maxine Waters (D-Calif.) were also targeted. An explosive device was sent to liberal billionaire George Soros earlier this week, and another suspicious package addressed to actor and Trump critic Robert De Niro was also found on Thursday morning.

This news comes about an hour after President Trump said the mainstream media is partially to blame for these attacks and for "a very big part of the Anger we see today in our society." Brendan Morrow

A day after Democratic politicians and a major news organization were targeted with explosive devices, President Trump is pointing his finger at the mainstream media.

The president tweeted Thursday that "a very large part of the Anger we see today" is caused by the "purposely false and inaccurate reporting" of the media, which he referred to as "fake news." Trump also warned the media to "clean up its act." The tweet came after several explosive devices were found addressed to Trump's political enemies and to CNN's New York office; the package to CNN was addressed to former CIA Director John Brennan. The tweet also came just as New York police were investigating a suspicious package addressed to actor and Trump critic Robert De Niro.

This is a notable shift in tone from Wednesday afternoon, when Trump delivered a speech calling for unity in response to the attacks. The president also spoke at a rally on Wednesday night and refrained from many of his usual attacks on the media. He patted himself on the back for his restraint, saying, "do you see how nice I'm behaving tonight?" Brendan Morrow
